The radio does not see the music on the phone

How to connect a smartphone to a radio

The first thing you need to check is the radio's support for a USB connection. To do this, inspect the device from all sides and find the connector labeled “USB”. If there are no labels above the ports, then you can find the desired input visually. Look at what the USB plug looks like and try to find a similar connector on the player panel. The most popular radios with USB support:

Pioneer 4018;
Suzuki Grand Vitara;
SP-4004;
Alpine CDE-131R;
Pioneer 7621;

After this, you should download your favorite songs to your smartphone. Please note that recorded music must be in MP3 format. Then connect one end of the cable to the phone and the other to the radio. A notification about connecting to the player should appear on your phone screen. Open the top notification shade and go to USB Storage or Connection Method. The names of the tabs depend on the smartphone model, as well as the Android version. Here, click on “File Transfer”.

USB operating mode - File transfer

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.

Open the Bluetooth section and try to remove your car from its settings

This method is quite common, since very often we have to resort to removing devices from the Bluetooth list of our mobile phone, in order to thus reboot its functionality and repeat the connection again. Perhaps the problem lies in the device being overloaded or the connection being poorly connected; this method helps to reboot the system and troubleshoot problems.

After removing our car from the Bluetooth settings, we must repeat the pairing of the devices and try to find a new signal, most likely this time the connection will be more stable, this is similar to interference and problems that happen to a mobile phone, and very often we just need to reboot it to update the work system. It is believed that this method works most effectively and is what users of Bluetooth devices often resort to. To test this method, you should use the following instructions:

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.

Just launch the built-in Music and select the tune you want. Within a few seconds, the selected song will play from the radio.

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.

We hope everything worked out for you, if you have any difficulties, ask questions to our bot in the telegram channel: write. Even more interesting things on the ITPEN channel.

In this article I will talk about how to connect your phone via Bluetooth to a car radio. There is nothing complicated about this, and the method is available even if the radio does not support wireless technology.

Mobile phone connection not found or its connection not recognized

When connecting the device to the car, unexpected problems and connection errors may occur, which in turn depend on several factors and circumstances. One common problem is that your car is not compatible with a particular mobile device, resulting in poor audio transmission. Most likely, the radio installed in the car is too old, so the multimedia sound of the mobile device is not transmitted either through the speaker system or through the car's speakerphone.

Connecting via Bluetooth to the radio

I suggest you study step-by-step instructions on how to easily connect via Bluetooth to a radio and apply the knowledge gained in practice! First of all, let's create a pair between the smartphone and the radio. Both devices must have a built-in Bluetooth adapter and be visible to each other.

#1 Setting up Bluetooth on your phone

Before you start connecting your phone to the radio in your car via Bluetooth, make sure that Bluetooth is turned on on your smartphone. These steps are almost identical for iPhone and Android:

Go to settings and check the “Bluetooth” parameter.

Make sure that the option for your phone to be found by other devices is enabled.

Check in the settings so that the smartphone is visible at all times. Some smartphones are configured in such a way that they remain online for only a few minutes.
Important: if the connection with the radio is not established for some time, the phone may also go out of sight. The first time I struggled with this question for a very long time, forgetting about this nuance.

USB bluetooth AUX adapter

This is the best adapter option, since it uses the AUX output for high-quality signal reception and sound playback, and solves several problems at the same time:

Plays audio from a flash drive or phone;
Receives incoming calls.

The device is universal, since it is essentially an adapter from SD format to a USB device. This transition is where the operating principle of the device lies. When the adapter is connected, it receives power and plays digital audio. This pairing format resembles the operation of a wireless device.

This bluetooth adapter resembles a CAN adapter. The latter serves as a device to simplify car radio control. Modern cars have electronics with a CAN bus, which allows any information to be output to the car radio.

The main advantage of USB/AUX car radios is that they play music efficiently, accurately, and without stuttering or interruptions. Other positive qualities:

Stable work;
Small size;
Pairing with almost all radios.

Negative:

High price;
There is no aesthetics;
AUX-Output is always busy.

Bluetooth: hands-free calling in the car

My personal opinion: talking on speakerphone using the car’s standard speakers is very comfortable. Nothing distracts you from moving, your hands are free, and the wires do not get tangled. With the help of Bluetooth systems, you can not only receive calls, but also dial numbers.

The methods for connecting and setting up a speakerphone in a car via Bluetooth are the same as for connecting music. Many cars are equipped with a “Hands Free” system – this is what you need to connect to. Different models have many options: screen control, voice commands.

If you have strangers in the cabin, and you do not want the details of the conversation to be heard by anyone else, then you can purchase a wireless headset. We can recommend the following models:

For example, the budget option SmarTerra will cost only 350 rubles. They look like this.

We also suggest watching a short video review of this model.

Headsets from Sven and Xiaomi have also proven themselves well; each brand has many good models; when choosing, be guided by the amount you are willing to spend.

Chevrolet Lanos “LEGO 18+” › Logbook › Adding Bluetooth to the radio!

I'm surprised by people who use adapters like this: Link

At a minimum, it is more correct in this case to use another cheap USB adapter

:
Link
-
one
,
two:
Without any telescopic wires, chargers, etc... You stupidly insert it into the USB radio and that's it!

These adapters emulate a “flash drive”

, and the radio sees them as a regular USB
“flash drive”
with music
(i.e., by connecting to the adapter from your phone via
Bluetooth and pressing play on the phone, the sound is transferred to the adapter and played immediately by the radio)
. Plus, you can control tracks
both from your phone and from the radio itself!
Most radios will even display track titles
. Yes, and through this adapter you can even make hands-free calls (it has a microphone), but the quality is usually not great.

But I, like many people, don’t like it when a healthy “flash drive” sticks out of the panel (and you can accidentally break it off)

, so I advise you to put it directly inside the radio
(solder it to the board)
!

This is done very simply, there are no tricks to it, just look at the pinout of the USB connector:

Open the casing of the radio, find the USB input, open the bluetooth adapter, unsolder the male connector from the adapter (it is no longer needed)

and solder the resulting board parallel to the USB input of the radio:

We end up with something like this:

If the USB connector in the radio is located on the removable front panel

, solder the adapter board in the same way into the removable panel to the USB input
(if there is space in the socket)
, or simply connect the contacts coming from the USB connector on the removable panel in the connector connecting the panel to the body of the radio, and already solder to these contacts inside the carcass.

If you have a radio without USB

, then this can also be solved - take an adapter with an AUX output.
Solder to the AUX input of the radio (if there is none, already look at the options locally)
and look on the radio board where you can get +5V to power the board, and then throw the ground on the case - that’s it.

So, if anyone has problems with sound quality, look at your phone settings (Android version), or look for what’s leaking on the Bluetooth frequency - because of this device, the connection speed is reduced, and therefore the audio bitrate!

How to turn on and listen to music in a car via Bluetooth?

Listening to music from your phone in the car via Bluetooth is a real pleasure. To do this, just turn on music playback on your phone; some machines additionally allow you to control tracks from the screen or by voice. You can also use downloaded files from your playlist.

For me, however, it is more convenient to launch an online service, for example Yandex Music or Apple Music. When the question of how to connect an iPhone to a car via Bluetooth has been resolved, then Apple Music is the best option. The program is paid, but provides access to a huge library of music and has a user-friendly interface.

Another high-quality service is Yandex Music. The application is paid, but if you use a browser, you can listen to music for free. There is a nuance: on iPhone in Yandex Music, tracks do not switch automatically, which is very inconvenient.

But you can also use other services, there are more than enough of them: VK music, YouTube music, and so on. If you connect an Android phone >

Communities › Electronic Crafts › Blog › Installing a bluetooth module in a Pioneer radio

I have a tape recorder, PIONEER DEH-6310SD, everything about it is good, except that there was no Bluetooth audio input, but it doesn’t matter, my Ketai friends have special scarves that can perceive this signal.

It seems that everything is simple, the board is powered by +5 of the radio, the left-right channel is on the aux, but there is one thing, I didn’t want the phone to constantly cling to bluetooth, and for this it was necessary to output the AUX_ON signal and control the bluetooth module with this signal. But this is not so easy to do...

Controlled via the SPI digital bus with three signals.

TZ: If he sees the AUX signature, he removes one from the PA0 pin (turns on the bluetooth audio module), if he sees the TUNER or CDROM signature, he sends one to the PA0 pin, but with a delay of 15 seconds (so that if you suddenly choose the wrong source, the bluetooth is not lost telephone).

Everything seems simple, but the development of the project took more than one day.

The DATA CLK and STB signals of the mixer were sent respectively to the controller ports SPI1_MOSI, SPI1_SCK and SPI1_NSS. After this, the controller began to adequately perceive signals.

I used a 2SA733 PNP transistor as a key, connected the base of the transistor through two diodes and a 1kOhm resistor to PA0, the emitter to +5V, the collector through a 22ohm resistor to the plus of the board (I made an RC noise filter). Bluetooth itself eats almost nothing. The power supply turned out to be 4.4 volts. (apparently the pn junction of the transistor affected)

How to connect your phone via Bluetooth to your car: 2 comments

Good afternoon Please tell me why the radio is connected to the phone only for calls, but cannot play music!

Hello, Oksana! There are different problems, most often you need to delve into the phone settings. For example, in Android there is an item in the Bluetooth settings A2DP.

Before connecting your phone to the radio, you need to understand what connection methods are available. This determines which functions and capabilities can be used.

Why Wileyfox

The British smartphone manufacturer Wileyfox first appeared on the market in the fall of 2015, but very quickly managed to gain the trust of users and the attention of experts. Each device in the model range attracts with its stylish design, high quality assembly and materials, and excellent technical characteristics. And most importantly - low price.

Music lovers will certainly appreciate the Wileyfox Swift 2 Plus model for its powerful hardware and rich equipment, as well as for its low affordable price.

Connection options

Depending on the model and operating system, connecting the phone to the radio can be done in several ways:

via USB interface;
via Bluetooth;
via analog audio input;
via a radio transmitter;
via emulator.

For connections, use known good cables and wires.

How to connect your phone to the radio via USB

To connect your mobile phone to the car radio, you will need a suitable cable. After turning on the head unit, the handset screen will light up and music will start playing in the car. At the same time, the gadget’s battery will be charged. If the car radio was turned on in a different mode, then after connecting the plug to the USB port it will switch to the music player. A mobile phone connected to the standard radio via a USB interface must support operation in removable storage mode in the same way as a flash drive or external hard drive.

How to connect your phone to the radio via Bluetooth

You need to check which profiles are supported by devices before connecting to the radio via Bluetooth. To play music through your phone, you need the A2DP protocol. With support for the HFP/HSP profile and a microphone, the car radio will help you talk on the phone hands-free.

To be able to control music listening, support for the AVCRP protocol is required. Before connecting the phone, you should turn on Bluetooth on the radio. To do this, press the source switch button until the desired mode is selected. Then the car radio and phone (smartphone) are paired.

To do this, open the BlueTooth settings on the latest device. The handset must be visible to other devices, after which the search for the head unit starts. During setup, the gadget must be located next to the car radio so that problems do not arise.

After a few tens of seconds, a line will appear in the list, which may contain the model or brand of the player or the words Bluetooth, Music, Hands free or others. To connect, you must select the desired device by entering the PIN code when prompted. When the pairing process is completed correctly, the car radio will beep and its status will change in the Bluetooth settings, indicating that the device is connected.

After pairing, you need to check the music playback and the ability to make calls (if this function is available).

To do this, turn on music from your mobile phone. The sound should be output through the speakers in the car. Otherwise, the audio output channel via Bluetooth is checked. When you press the listening control buttons on the head unit, the tracks should switch.

To check the speakerphone through the radio, you will need an assistant with a second handset. He must call the phone paired with the autoplayer. When a call arrives, the caller's number or name will appear on the display of the head unit. The ringtone will be played on the phone itself. To receive a call, press the button with the handset icon on the radio.

AUX connector

Using this method, you can connect your old phone to a car radio that has an additional audio input (aux) to listen to music. If your mobile device is equipped with a standard 3.5 mm jack, then you will need a shielded stereo cable with appropriate plugs for connection. One of them is inserted into the socket on the phone, and the other into the car radio with AUX.

If the handset is equipped with a non-standard socket, then you can connect it to the AV radio input or via AUX by making an adapter cable. It requires an audio cable with a stereo jack or AV connector and a standard headset. Both headphones are cut off, and the ends of the cables connected to them are stripped.

Common wires have the same color. They are soldered to the audio cable wire connected to the negative terminal of the plug. The remaining two wires are the audio output from the phone. They connect to the left and right channel pins of the audio cable. The advantage of this method is the possibility of hands-free communication through the radio.

Transmitters

Music from the phone can also be broadcast via radio to a car radio, which has neither a USB port nor an audio input, through a transmitter. It is powered by the cigarette lighter in the car. The choice of transmitter depends on the design of the phone. If your smartphone does not have a headphone jack, then you should use a Bluetooth transmitter. If this is the case, then to connect to the radio you need an FM transmitter with a linear audio input or a USB port.

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:

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.

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.

Connection features

It is necessary to take into account the operating features of different mobile devices with Android and iOS before connecting the phone to the radio in the car. This will avoid additional problems associated with the inability to play music or the unavailability of various functions.

For Android

Smartphones with Android version 5 and newer do not have a removable disk mode. In this case, to listen to music in the car from such a gadget, you will need a car radio that supports the MTP protocol or is compatible with the proprietary Android Open Accessory 2 package. This feature is available in recently released radios from JVC and some other manufacturers.

Depending on the model and specification of both devices, some control functions may only be available on the Android smartphone's player. From the radio you can, for example, switch between tracks. To check for compatibility, you need to connect your Android smartphone to the radio and select the MTP protocol. If it supports Android Open Accessory, then music will start playing. In rare cases, you may need to enable USB debugging mode.

For iPhone

It is worth considering that the radio must support work with similar devices (as well as IPod). This may be indicated by an icon on the front panel and the presence of the required options in the menu and source list. Only in this case can you listen to music from your iPhone. To connect your iPhone to the radio in your car via USB, you should use the proprietary cable included with the gadget. When you install an additional application from the App Store, you will be able to control the radio from your phone.

About Wi-fi and more...

Yes, radios can be connected to Wi-fi. To do this, you need a built-in Wireless interface (REALTEK 8188EUS moodle, for example). If there is a built-in wireless data transfer interface, the user will be able to connect to the Internet by distributing a Wi-Fi connection from a smartphone, or by gaining access to the nearest point (for example, near McDonnalds).

You can also use special adapters, of which there are a lot. They use any USB input in the car and “distribute” a Wi-fi point. Such devices hold a charge for about 4-5 hours. Here you can read about a method that will explain how to connect a modem to a radio on Android.

We buy an adapter on Aliexpress or ebay;
We connect it to the USB input (cigarette lighter turned into USB or the output on the front panel of the radio itself);
Turn on the modem and wait until the device operation indicator lights up;
On the car radio, turn on the search for a wireless network and look for an adapter;
After finding the adapter, you need to enter the password (standardly it is 12345678, if it doesn’t work, look at the instructions for the modem) and connect to it;
We use the Internet.

Further in the article, the reader will be able to find information on how else you can connect the Internet to the radio on Android.

Method using a 3G modem

To implement this method you will need:

Actually 3G or 4G modem;
USB input available.

Sometimes difficulties arise with modems; they do not want to perform their functions. This is possible with the new 4G modem from Megafon, and old modems from Huawei or ZTE work perfectly in such conditions.

And again the instructions:

First you need to find the USB input from the radio;
Then connect the modem to the Android head unit;
After this, you should go to the radio settings and enter the necessary information on the telecom operator.

Example: MTS; APN:internet.mts.ru; Login: mts; Password: mts. The setup is complete. Now you can use the Internet, Yandex and Google maps and other applications that require an Internet connection.

We can only hope that after reading this article, users of Android radios will not have any difficulties connecting to the Internet or smartphone. The main options have been discussed here, although each car radio requires an individual approach.

If not, write the phone and radio model in the comments. We will try to help.

I have an htc one, and there is a radio in the car, with USB, aux, bluetooth, etc., is it possible to connect my phone via USB to the radio? I can't connect. Are there any instructions specifically for this model?

Tell me, if the Pioneer PI 803 NEW GPS has a USB output on the front side, then only the music and video flash drive is connected to it? Or you can connect a mobile phone. telephone? In the radio menu there is a phone connection service. When I connect via BT, this connection service does not work. The answer is that no connected devices were found, although the VT works fine, music and phone. I don’t understand what kind of connection service this is and how to use it. Maybe via USB? But I'm afraid to connect without consultation.

Hello everyone, please tell me I have an AVİC MRZ007 question: what kind of cables are needed?

Samsung galaxy j3 2006 phone with android5.1.1. Philips cem 2101g/51 radio. When you connect the phone to the radio, the first one emits a beep and lights up the charge level indicator. It does not show any connection type items.

In modern vehicles it is difficult to imagine the absence of a car radio or other device that produces sound. But product manufacturers do not limit the functions of their devices to this. The Japanese company Pioneer connects the car radio to the linear input, providing the ability to connect many devices from external sound sources. The article suggests learning how to properly connect a Pioneer car radio in order to expand its capabilities.

Bluetooth Flash

This is a “flash drive” with Bluetooth function. It is inserted into the USB input of the receiver and transmits data from Bluetooth to it. How it works? The flash drive has a small internal memory. Everything that Bluetooth Flash receives via Bluetooth (music, audiobook, telephone conversation) is recorded on it. The car radio sees the Bluetooth Flash like a regular drive, reading data from the internal memory.

Inexpensive;
Compact;
Neat and beautiful;
Can be used not only with a car radio, but also with any one that has a USB input.

The sound may “hiccup”, i.e. disappear for some time. Possibly related to recording speed, or may depend on the playback device;
Not all radios read this kind of flash. For example, my car's radio could not find a common language with it. No data from the internal memory was played back. And, for example, by connecting it to TV, the device started working.

We can recommend the device to those who do not have an AUX input in their car (or really don’t want to remove it). Apart from a USB input, this “Flash Drive” does not need anything else. But be aware of the “icks” and incompatibility with some radios.

Wileyfox Swift 2 Plus

The model with a 5-inch IPS 2.5D display with HD resolution features a stylish, attractive design of a thin metal body. The smartphone also boasts modern technical characteristics. No problems with simultaneous processing of the most resource-intensive applications, for example, when playing music files and running a navigator, is ensured by a powerful 8-core Qualcomm Snapdragon 430 MSM8937 processor, built on a 64-bit architecture and operating at a frequency of 1.4 GHz.

The phone is equipped with 3 GB of RAM, which also facilitates the ability to multitask and load several applications simultaneously without experiencing problems with the system. To store audio, video and other data, the user is provided with 32 GB of internal memory. If this is not enough, there is the possibility of using a microSDXC card up to 64 GB. Thanks to support for Quick Charge 3.0 fast charging technology, you will forget about the problem of a low battery - just 10 minutes of recharging, and the battery will receive 25% of its capacity!

The smartphone is equipped with a Fingerprint fingerprint scanner to ensure maximum security of your personal data in the device, as well as an NFC module for communication between different devices over short distances, for example, with accessories or with other smartphones for data transfer, and contactless payments.

You can order the Wileyfox Swift 2 Plus smartphone for only 11,990 rubles on the official website.

Types of devices

Signal transmission from the phone to the standard radio can be organized in several ways, each of which has its own type of device. Each option has its own strengths and weaknesses, knowing which anyone can choose a Bluetooth adapter for their car that suits them.

FM transmitter

The FM transmitter is quite popular among motorists in Russia, despite many shortcomings. It is a device that is inserted into the cigarette lighter to play music from the radio or receive calls from the phone. Since the transmitter is powered through the cigarette lighter, it will be busy all the time. And this is not the only drawback of the FM transmitter.

The transmitter itself is quite large and rarely looks neat, so many people consider it not aesthetically pleasing. But the main disadvantage can be considered the possibility of crossing FM waves. Cars in the next row may accidentally (or deliberately) listen to the same wave by tuning into it through their car radio. And if there are 2 cars nearby that use similar devices and try to listen to the same wave, then interference, hissing occurs, and the sound disappears.

Ordering an FM transmitter on the Internet is not the best idea, since manufacturers often send models with limited functions, for example, they can be used for talking while driving, but you will not be able to connect audio files from your phone.

The popularity of transmitters is due to their low cost and wide distribution. You can buy such a device at almost every gas station and in all auto supply stores.

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.

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.

Connecting devices using AUX

Connecting using the AUX output is considered one of the first options used for connecting external media to the car radio. Already cassette recorders had such outputs, which made it possible to connect different devices to them. This output is made in the form of a regular round connector with a diameter of 3.5 mm - the kind that is now used on phones to connect headphones.

To connect the playing device and the phone, a cable is enough, at both ends of which there are plugs with a diameter of 3.5 mm, which are inserted into the radio and smartphone.

Video: how to connect a mobile phone to a car radio using a headphone jack

Such a connection implies the use of a phone player, which means that control can only be carried out from it. In other words, the radio plays the role of an amplifier, which means that it can only be used to adjust the sound level.

The disadvantages of this connection method are:

presence of cable;
inconvenient controls, since to switch the track you have to pick up the phone every time;
The phone discharges during playback.
