How to connect a phone to a car radio via USB, Bluetooth, AUX

Connection methods

I want to immediately note that there are many ways. At the same time, sometimes several connection options can be used on one radio. If one method does not see, use another. Or choose the one that you consider the most practical and convenient.

It doesn't matter what kind of car you have. This could be Renault Duster, domestic Lada Vesta or Lada Granta. Some have a radio tape recorder purchased separately, others make do with the standard system.

There is even a variety of radio tape recorders themselves. There are several most common brands:

• JVC;
• Samsung;
• Coonwood;
• Pioneer;
• Prology;
• Sony;
• Alpine;
• Terra;
• Sho Me, etc.

There are different versions, models and generations. Even with a Chinese radio of unknown origin purchased for Chery Tiggo, sometimes you can connect your Android smartphone in a couple of minutes. Brands and models do not play a key role here. The task is always the same. You need to somehow connect your phone to the system.

Conventionally, all methods can be divided into wired and wireless.

Today we will look at the following connection methods:

• Music via bluetooth in an android car

• Using a USB cable. Relevant, in demand, not very difficult. Although with its drawbacks;
• Via AUX. Also a common option with its own characteristics;
• Via radio. Yes, you can even connect like this. You will soon find out what we are talking about;
• Using the bluetooth system. Wireless connection category;
• Through the tulips. Not the most popular method, but it cannot be ignored.

Now let's try to briefly but clearly consider each option separately. And then everyone will be able to draw their own conclusions and make a final decision.

USB

Objectively one of the most relevant connection methods. A standard USB cable allows you to connect a phone or just a computer flash drive.

There is a special cord, one end of which looks like a USB connector, and the other is designed to connect to a phone. Please note that old radios cannot synchronize with smartphones, so they treat the phone purely as a storage device, that is, a memory card.

After connecting the devices with a cable, in the settings of your gadget, look for the section with a USB connection. Next, the data transfer menu starts. This will allow the audio system to accept and play audio files available on your phone. But control is only available through the radio on older systems. If it is more modern, you can synchronize and use the device somewhat more efficiently. This allows access to control simultaneously from two devices. Another plus is that while playing, the phone will be charged in parallel. It may be slow, but at least the smartphone will not lose its charge.

There is only one minus. This is a dependence on the cable, which can get in the way. If the cord is short, when a call comes in you will have to turn off the mobile phone, and then reconnect everything and start the music.

If you have USB, it is better to take a fully-fledged flash drive, record your favorite music on it, and leave your smartphone at hand for other purposes.

AUX

This is a special connector available on car radios. Almost the first functionality that allows you to connect a phone and an audio system in a car. If there is no AUX on your car, this is somewhat strange, since such connectors have been used since the days of cassette tape recorders.

It is actually a round shaped plug measuring 3.5mm. This is the one you use when connecting headphones. It is not difficult to find the appropriate cable in stores. And the connection is incredibly simple. Take a cord, one end goes to the phone, and the other to the radio. That's it, you're ready to listen. The only control element here is the smartphone itself. You will have to switch tracks through the built-in player or application. That is, the audio system itself acts as a speaker with an amplifier, where you can adjust the volume.

The option is very good and convenient. Extremely easy to connect and disconnect as needed.

Bluetooth

A modern wireless connection option that allows you to connect two devices without the use of cords and cables.

• But here it is important that bluetooth is on the radio itself. Your smartphone probably has it;
• Next, the port on the audio system is turned on;
• At the same time, Bluetooth is launched on the phone;
• The devices are interfaced with each other;
• This allows you to create integration between devices;
• The smartphone is retracted to the side, since control is carried out through the audio system;
• The connection makes it possible to listen to music and watch videos;
• In some cases, the radio can be used as a speakerphone.

Of course, the smartphone will not charge, but the battery wear will increase. But not so much that after a couple of hours of operation the battery runs out.

Convenient, practical, functional and versatile. But it is suitable only for modern car radios.

Transmitters, tulips and emulators

Now let's briefly look at 3 more options. They are not the most optimal, but still have a right to exist.

• Emulator. A universal music reader with connectors for AUX and USB. At the back of the radio there is an ISO output to which the emulator is connected. The cord is included. The connection is not the most convenient, but then you can use your phone, MP3 player and flash drives;
• Tulips. If the armrest has RCA jacks (tulips), you can use them to connect to your phone. It is important to take a cable with tulips on one end and a 3.5 mm headphone jack on the other. Moreover, the connection does not always work clearly by color. Try different combinations;
• Transmitters. These are devices that connect the phone to audio systems, even with just a regular radio. It is the radio receiver that is needed here. You can find out more about transmitters here.

That's all. I think we've covered all the existing ways to connect two devices.

5 ways to connect your phone to your car radio

Connecting the phone to the radio is carried out using several methods:

1. Using a USB cable, which is connected to the corresponding connector of the head unit. The tape recorder can play content recorded on the smartphone's storage device. Control is carried out using the car radio menu or mobile device.
2. Via Bluetooth wireless communication, the technology provides improved sound quality.
3. Using a cable installed in the AUX connector. The technique is not characterized by high signal quality; it is used for switching external players.
4. By connecting a radio frequency transmitter.
5. Using an emulation unit that allows you to connect various equipment to the head unit.

Via USB

To connect your phone to the radio via USB, you need a connecting cord. The USB input is located on the front panel of the radio, center console or in the glove box (depending on the car model). After connecting the USB cable, you need to enter the smartphone menu and enable data transmission via the serial interface. The driver can listen to music in the car via USB (recorded on a storage device), some of the head units are used to amplify the signal, and melodies are played on the phone.

Is it possible to charge a smartphone via a USB radio?

By connecting the phone to the car radio via a USB plug, the driver is able to charge the built-in battery. Please note that the car connector does not support accelerated charging protocols. The disadvantages of the connection method are the dependence of the signal quality on the cable material and the lack of support for the speakerphone function; when a call comes in, you must disconnect the connecting cord.

Via Bluetooth

If the driver does not want to use wires, then you can connect the phone to the radio via Bluetooth (if there is a controller in the tape recorder). When connecting to a radio via Bluetooth, you need to make sure that the paired devices support the same protocols (for example, A2DP). To connect your phone to the radio in your car, you need to enable scanning mode on your smartphone, then select the multimedia center and confirm the connection.

The driver can connect a smartphone to the standard radio by searching for devices through the player menu; the Bluetooth module in the phone is first turned on. The head unit scans the airwaves, identifying compatible devices. You must select the found smartphone and then confirm the connection. The user can listen to music content through the radio, as well as use.

Via AUX

The AUX switching technique is used to pair older speaker devices and mobile phones. The connection requires a cable equipped with a plug with a diameter of 3.5 mm. One end of the cord is installed in the smartphone, the other is plugged into the Aux port. To play music content, you need to turn on the player built into your smartphone. Control is possible only through the phone; the tape recorder has a volume control and an equalizer.

You can transfer music from your phone to the radio using the AV acoustic connectors located on the rear of the car radio. For switching, a cable with a double “tulip” at one end and an AUX plug at the other is used. The cord is connected to the player and the mobile device; when making connections, you need to try different options for connecting the “tulips” to the connectors. Some of the radios have similar video input connectors; connecting to the plugs does not allow sound to be transmitted to the amplifier.

Via transmitters

If the head equipment is not equipped with connectors for connecting external devices, then the driver can connect a mobile phone using transmitters.

The device is a wireless transmitter that transmits a signal in the ultrashort wave range.

The product design has ports for connecting a smartphone; the signal is received by the tuner of the multimedia center.

Bluetooth transmitter

The car radio product is equipped with a built-in Bluetooth transceiver, with which a cellular device is interfaced. The transmitter must be connected to the vehicle's on-board power supply (for example, using a 12 V socket or cigarette lighter located on the center console). The mobile device is paired with the transmitter, and then the tape recorder is tuned to the frequency of the signal broadcast.

The equipment is designed with multiple frequency ranges to reduce the impact of radio frequency interference. Some products have a liquid crystal display, the user can see the status of communication channels and the carrier frequency. Starting and stopping the playback mode and switching tracks is done using buttons on the smartphone, the sound volume is adjusted through the car radio. Transmitters with a Bluetooth controller are produced by Chinese manufacturers; the equipment does not have high quality sound transmission.

FM transmitter

Manufacturers from China offer transmitters with USB or AUX ports, then the signal is transmitted via radio. When using the AUX pad, control is carried out through the cell phone menu.

Transmitters with a USB plug are equipped with their own button block.

The user can switch songs and stop playback by pressing individual keys. The design of the equipment allows you to charge external batteries, but the current in the circuit does not exceed 1 A (at a voltage of 5 V).

Via emulator

The emulator unit is connected to the ISO connector located on the back of the head unit. The equipment can work with compact MP3 players, USB drives or mobile devices. The kit includes a patch cable that runs from the rear wall of the car radio into the glove box or niche in the center console. The emulator ensures compatibility of the protocols used in the head unit and external equipment; playback is controlled using buttons on the smartphone body.

This function allows the radio to play the melodies available on the phone, no matter where they are located - on the SD card or in the internal memory.

How to play music

Immediately after connecting, the radio will start FM radio - do not pay attention. The way you control songs depends on the year the player was produced. On older radios, this can only be done using the built-in buttons. And on newer models it is possible to listen to songs directly from your smartphone.

As you can see, the cable method works great, but it has one huge drawback - the cord constantly gets in the way while driving. It is best to record musical compositions on a regular flash drive and insert it into the radio. Of course, you can’t control the player from a smartphone here, but you can improve driving safety. You can also install a navigator on your phone and listen to driving directions from the car speakers. Another way: How to connect a phone via Bluetooth to a radio tape recorder Thus, after reading this material, you can easily connect your smartphone to the radio tape recorder. It is worth noting that when you connect your phone via a USB cable, you can select the charging function, then the device will gradually charge the battery.

As we know, inexpensive car radios have a limited number of functions. You can expand their capabilities by connecting your smartphone using one of the available methods using AUX, Bluetooth or USB. New generation phones are equipped with modern devices that provide special options for connected equipment. Automakers, in turn, create models that can function in integration with phones, but in order to use useful functions, you need to be able to correctly connect and configure the device.

How to connect devices via USB

One of the most common options is to connect using a USB connector. Its presence provides access to information located on a standard computer flash card.

The disadvantages of connecting the phone to the radio via USB include the presence of a cable that stretches from the car radio to the smartphone

But the USB connector can also be used to connect a smartphone using a special cable. At one end there is a connector that allows you to connect to a phone, while at the other there is a USB plug. Integration of mobile devices with simple radio tape recorders is impossible, and therefore the latter are used only as an ordinary flash drive.

To play music, just connect the cable to the smartphone connector and the radio input. Then you need to select the “USB connection” item in the gadget settings and activate the “Data transfer” mode. This will allow the radio to read all files containing music. Now you can listen to your favorite songs without any problems. In this case, the listening modes are controlled from the radio.

On more expensive radios, integration with a gadget is possible, which makes it possible to control music modes from any of the tandem participants. In addition, applications installed on the smartphone, for example, some special player, can be launched. But in this case, the car radio acts as an ordinary amplifier.

Video: how to connect USB, AUX and head unit

The connection method described above is quite convenient. In addition to the fact that it becomes possible to manage files using the radio, the smartphone is also recharged.

The disadvantages of this option include the presence of a cable that must be stretched from the radio to the smartphone. And if the connecting cord is short, then the phone will not reach the special stand, so it will constantly fall.

What is Bluetooth, AUX and USB

Budget car radios have a limited list of functions. Usually they do not have special connectors that allow you to connect an external device and listen to music. To remedy the situation, you can purchase an adapter.

What are Bluetooth, AUX and USB. At their core, these are technologies created to transfer data from one device to another.

Bluetooth is different in that it allows you to connect gadgets by wirelessly transmitting information.

Each method of transferring data from a phone to a car radio has its own technological features.

How to listen to music in the car via Bluetooth

The most profitable option for connecting a smartphone to a car radio via Bluetooth. The technology allows you to use the phone's options in full. The system allows you to synchronize the operation of the radio and audio transmitter.

The connection method is also advantageous because while using the phone, you can communicate remotely without using your hands. To make the connection, you can use the instructions from the car radio.

Such a device always has a manual in Russian, where all the steps are described in detail with pictures:

1. The required mode for receiving information is switched on on the sound-reproducing device;
2. Select Bluetooth from the phone menu;
3. A list of available devices appears on the screen, the one you need is selected from the list, and the connection is made.

One glance at the phone screen is enough to control the correct functioning of the connection. The Bluetooth icon should glow white or blue. If there is no connection, it remains gray.

This method of transmitting information is advantageous because there are no wires. Several devices can connect to one phone and receive data at once.

The only disadvantage of Bluetooth transmission is that it quickly drains the phone's battery. After a short period of time it will have to be recharged; if there is no car charger in the car, the driver risks being left without communication.

Video connection instructions

How to properly connect your phone via Bluetooth in this video:

Connecting a smartphone using AUX

This type of connection allows you to use the car radio as an amplifier, while the music is played back by the phone.

Audio information can be obtained:

1. From the Internet online;
2. On the radio;
3. From recorded and saved files.

To make the connection, you only need an AUX adapter with the appropriate connector.

This type of connection between the telephone and the car radio is not beneficial:

1. The energy reserve on your smartphone quickly disappears;
2. The phone cannot be recharged while playing music via the AUX connection;
3. Additional connected wires in the car create inconvenience.

Advantages of AUX connection:

1. Does not require complex settings, universal;
2. The selection of musical compositions is made from a mobile device;
3. The ability to create a playlist to your own taste;
4. Ease of Management;
5. The ability to organize a speakerphone through which everyone present in the car can communicate;
6. Works on the simplest devices.

During a call on the phone, the transfer of music to the radio stops. Some consider this an inconvenience, while others consider it a plus, since loud sounds do not interfere with hearing the interlocutor.

Video instructions for connecting two devices

This video describes in detail how to connect two devices to listen to audio materials:

Pairing your phone and radio via USB

The USB adapter is a universal tool; it can be used to connect various types of devices. To transfer audio from a phone to a car radio, certain connectors (sockets) are required through which the adapter is connected.

The USB connection allows you to control the phone through the radio and in the opposite direction.

While data is being transferred to the playback device, all other mobile phone applications remain available and can be used.

Note: How to bleed ABS brakes for one person

To connect via an adapter, you do not need to perform complex manipulations or additional settings. Devices begin to “see” and perceive each other automatically. Some models ask the administrator for access permission, then no difficulties arise during operation.

The positive aspects of using a USB connection to connect a phone:

1. The phone's battery does not drain as quickly as when connected via Bluetooth.
2. The mobile phone requires recharging less often, since while transmitting information to the radio through the adapter, its battery is simultaneously recharged.
3. The phone can be controlled through the radio screen, and the playback device through a mobile phone.
4. During the transfer of information, all other applications and functions of the phone remain available and can be used. This is especially valuable when you need to make a call or use the navigator in your smartphone.

There are not many disadvantages to this method:

1. A constantly connected and hanging wire can get in the way;
2. Old radios do not see “audio files” in new phone models or cannot play them.

Video manual for connecting devices

When the user does not understand exactly how and into which socket the USB cable should be connected, they should study the manual, which clearly describes all the actions that need to be performed.

The video instructions describe how to connect your phone to the car radio:

What to do if the radio does not “see” the smartphone

There are often cases when those who like to combine driving a car with listening to fashionable music encounter a problem: they cannot connect the radio and smartphone via Bluetooth, USB port or AUX connector. Why is this happening?

Why can't I play audio files?

If all attempts to connect the phone to the radio are unsuccessful, then you need to perform a series of checks.

1. Make sure the connecting cable is in good condition. It can be checked by connecting the phone using the same cable to the computer. If the connection is normal, then you need to look for the reason in something else.

   
   To check the cable, connect the phone to the computer using it

2. Check the serviceability of the radio connectors. Here testing is carried out according to the same scheme as in the first case.
3. Make sure that this radio model supports the software installed on your smartphone.
4. Find out if there are viruses on your phone. In this case, the radio reader may simply “refuse” to transfer files containing viruses.

What to do so that the device can transfer data

Possible methods for solving the problem are selected based on the causes of the breakdown:

1. You can start by rebooting your phone - the possibility of a system failure cannot be ruled out.

2. Pull the connecting cables out of the sockets and insert them again, shaking them slightly. This will help if there is simply poor contact at the connection points.
3. To check, try connecting another device to the radio.
4. Flash your phone so it can connect to your car radio. These programs can be found in large quantities on the Internet. After updating the software, the problems may disappear.
5. When connecting via bluetooth, you may need to enter a PIN code on both devices. Most often it is four zeros or four ones.
6. You can also try a factory reset and try turning on the device again.

Connecting your phone to the radio via USB, AUX and Bluetooth is a simple operation, which, however, has its own characteristics. Compliance with all connection rules guarantees the quality of operation of the devices and the pleasure of playing music or listening to the radio while in the car.

Hi all! Just think, just recently, having a car radio capable of playing CDs in a car was something incredibly prestigious and inaccessible to most mere mortals. But technology is developing at an amazing speed. And now, to play your favorite song in the car, you only need to have a smartphone with you.

Today we will talk about how to connect your phone to the radio. We will try to consider all the current methods that allow you to connect these two devices together and be able to listen to music.

I would like to note that in some cases a smartphone allows you to easily access a huge media library even without a modern audio system in your car. A smartphone and one of the connection methods that suits you will help here.

What problems can you encounter?

Inexpensive car radios are rarely equipped with the devices necessary to connect to a telephone. Some models can be equipped with an adapter that allows you to receive data transmitted from your phone.

On the subject: What is a tachograph and why is it needed in a car

When transmitting data to the car radio via Bluetooth, AUX, the phone battery drains quickly. After a short period of time it will have to be recharged.

What can be concluded? Connecting a phone to a radio is possible in three available ways, however, despite the simplicity of this process, not every user is able to connect two devices without watching video materials and studying instructions.

Smartphones store a large library of your favorite music. To play tracks from your phone in your car, you need to connect the gadget to the car radio. We talk about current methods of synchronization between a car radio and a smartphone.

USB connection

Using a USB connector is one of the most popular methods of communication between a radio and a mobile device. This device allows you to play music from a regular computer flash drive. However, in addition to a flash drive, a smartphone can easily be connected to this connector via a cord.

This cord has a regular USB connector on one end, and a phone connector on the other. Outdated car radios do not have the ability to be fully compatible with a phone, and therefore the phone is used in them as a regular flash drive.

To play files from your phone, you need to connect your mobile phone and the radio with this cable, then find the “USB connection” item in the mobile phone settings and launch the “Data transfer” function. As a result, the radio will start playing all music tracks from the mobile phone.

However, these files can only be controlled from the car radio. But if the radio is more advanced, then it will be able to be fully combined with the phone, and then control can be carried out from both devices. Moreover, you can run various useful applications on your mobile device, for example, some special player, and then the radio will only work as an amplifier.

The connection via a USB cable is very comfortable: files are regulated from the radio, the recording sounds, and the phone is also being charged at this time. Of course, charging is slower than from a charger, but it is convenient that the phone, while playing music, not only does not discharge, but also receives charging. Let it be small, but still.

The main disadvantage of this connection is the dependence on the cord. It will have to be extended to the smartphone, which may create inconvenience for the driver. And if the cord is also short, then when making calls you will have to disconnect it.

AUX

Car radios have AUX - a small round plug with a 3.5 mm jack that is used to connect headphones. To connect a smartphone, you need to purchase a special AUX cable (costs 200-300 rubles) - there are two 3.5 mm plugs on both sides of the cord.

One connector is inserted into the connector on the car radio, the second into the smartphone (instead of headphones). This completes the connection process: launch the desired song on your mobile device. Music control - play, pause, switch tracks - is done through the player on the phone. The car radio acts as speakers and transmits sound from a smartphone. You can also adjust the music volume level through the radio.

Common problems during work

Remember - there should be no problems connecting your phone to the head unit! It's a simple and quick procedure! If the connection fails, most likely the problem is in the settings.

USB cable

A popular way to connect a phone to a car radio is a USB cable. The radio has a USB connector into which gadgets can be connected: smartphones, tablets and flash drives with music.

To connect a mobile device, you need to purchase a special cable, where one end has a USB connector (for connecting to the car radio), the other for connecting to the phone. When choosing a cable, you need to pay attention to the connector for connecting to the smartphone - it must match. Now smartphones use microUSB and Type-C connectors, and iPhones use Lightning connectors.

After connecting the gadget to the car radio via a USB cable, you need to go to the audio system settings and select the USB connection type. On some radios, the smartphone will be detected automatically and without additional settings.

If your car radio has a control display, it will display a list of music tracks from your phone. The gadget acts as a storage medium, like a flash drive. Music control - play, pause, volume control, track switching - is performed through the car radio.

Modern radios have a synchronization function with third-party devices. After connecting your phone via a USB cable, you can control your music from both the car radio and your smartphone. The peculiarity of this type of device synchronization is that when the phone is connected via USB, the slow charging mode is activated.

Bluetooth

This type of phone connection to the car radio does not require the purchase of additional equipment or cords. Modern car radios have a built-in Bluetooth wireless module. It allows you to synchronize between two devices: a radio and a smartphone.

Thanks to this, car owners can talk on the phone through the speakers in the car and listen to music from the gadget. To perform synchronization, launch Bluetooth on the car radio and smartphone. Playback control is carried out either through the phone or through the radio - it depends on the car’s audio system.

6). Select your car's speakerphone from the list of detected Bluetooth devices

After the phone has detected the hands-free system of your car, on the screen of your device you should find in the list of detected equipment available for connection, the “Hands Free” system or the like. system.

In our example, the phone detected the Hands Free system of the Toyota Camry. After this, in our example, we had to click on the “Hands Free” inscription to begin the process of connecting the phone to the car.

Once you select the device you want to connect on the phone screen (or after the infotainment system detects your phone), you must enter a password (PIN) on your phone to pair the two devices.

As a rule, all cars equipped with a speakerphone or a system for listening to music from wireless devices are supplied directly with a password generation system for pairing the car with a phone.

If your car is equipped with an infotainment system screen, then. after these devices find each other, the word “password” should be displayed on the screen of your car, which you must type on your mobile phone to finally pair (connect) the devices.

If your car is not equipped with a screen, but has a hands-free option, then refer to the vehicle manual, which should indicate what password you need to enter to connect the phone to the car.

For example, many car models often use simple passwords that are already set to , “1111”, etc.

You can also set (create) such a password manually if you search for devices directly from your phone.

FM transmitters

An FM transmitter is a small device that connects through the cigarette lighter. It is used to play music from smartphones, tablets and USB flash drives.

The FM transmitter (also known as a modulator) supports two types of connection with gadgets: via USB and via Bluetooth. Connect the device to the modulator, and the latter will begin sending a signal over the radio channel. To synchronize between the car radio and the modulator, you need to tune to the transmitter frequency. After this, audio will begin playing from the phone that is connected to the FM transmitter. It is important to note that since the signal is transmitted over FM, the sound quality will be worse than in previous methods.

The life of a modern person is closely connected with smartphones. But few phones today are used only for conversations; here you can communicate on social networks, use useful applications for paying for purchases, receive various services, listen to music. If you connect your smartphone to your car radio, you can fully enjoy your favorite songs. But how to do this if the Bluetooth option is not available?

Via AUX

This is the easiest and fastest way to connect to your car's audio system. Moreover, it is suitable even for the oldest radios. The main thing here is to find a standard 3.5 mm port on the radio. On standard equipment, you need to look for it inside the glove compartment and armrest. Almost all phones have this output.

Then you just need to purchase an AUX cable with two identical Jack-3.5 mm plugs on both ends.

Depending on the quality, its cost is 50-250 rubles.

Connecting the system is quite simple. You need to follow this algorithm:

1. Plug one plug into the AUX port of the radio, the other into a similar input of the phone.
2. Switch the audio system to the desired mode.
3. Play selected music on your smartphone.
4. You should manage your tracks from your phone.

Some new iPhone models do not have the required port. In such situations, you can purchase a Lightning-3.5 mm Jack cord.

How to connect

A logical question arises: how to connect a third-party device to the radio via a linear input? It's actually quite simple. There are several ways to do this:

1. Purchasing an adapter with a Mini Jack 3.5 mm connector
2. Buying an audio Bluetooth adapter

These devices have become very popular because with their help you can significantly expand the functionality of even the most outdated radio.

Here you just need to tune the audio player to the frequency of the operating transmitter. This will allow you to listen to tracks directly from your smartphone.

The device itself is powered by a cigarette lighter. It has the usual set of functions of an MP3 player that can play information from flash cards. For this purpose, there is a full-fledged USB port and a slot for SD cards. In this case, music playback is controlled directly on this device.

The FM transmitter has the following characteristics:

1. Some models play music, read USB flash drives and SD cards. In addition, they can serve as devices for remote communication.
2. Suitable for working with old radios without a Bluetooth module or AUX port.
3. Powered by cigarette lighter or USB input.

To activate the device you need to follow the following algorithm:

• connect the translator to a power source;
• select Bluetooth mode using the switch on the case;
• establish a connection with an FM device by selecting its name from the smartphone list;
• tune the radio to the FM frequency at which the transmitter operates.

After completing the settings described above, the device will be fully connected. Then you can easily select the desired song through any player on your smartphone and enjoy the music.

Emulator

This device makes it possible to play sound from USB drives, SD cards, and receive information from a smartphone via an AUX cable. There is a special connector for it, which is located on the back panel of even old radios. As a last resort, you can use a special adapter for connection.

The head unit recognizes the emulator as a CD changer. When choosing a device via the Internet, it is important to find out whether a particular model is suitable for a particular car. Certain protocols must match here.

The emulator is a universal device that can be used to significantly improve music playback in a car that is equipped with an inexpensive radio and speaker system. This device will significantly increase the functionality of a simple audio player to the level of expensive equipment.

USB connection

The most common connection method is via a USB port. To connect, you will need a regular USB cable, which is used to connect the smartphone to the computer. At one end of the cord there is a micro-USB plug for the phone, at the other there is a standard USB connector.

To integrate the radio with the gadget's operating system, you need to go to the smartphone settings and activate the data transfer mode. After this, the radio will have access to music files. In this case, the radio will be responsible for selecting tracks and adjusting the sound.

The latest generation car radios make it possible to control the process of playing tracks both from their own menu and from the smartphone menu. In the latter case, the user can open a player application on the smartphone, launch a playlist, and use the radio exclusively as a simple amplifier.

REFERENCE. A USB connection allows you not only to play music tracks from your smartphone, but also to slightly recharge the device’s battery.

If there is no contact between the radio and the smartphone, or the phone is charging but the radio does not perceive it, try using a different cable. Most likely the cable is damaged or the port is broken. And make sure that the “Data transfer” function is turned on on your smartphone.
