Many owners of old generations of radio tape recorders, and to be honest, many new ones (for example, in VOLKSWAGEN), do not have the ability to connect a USB flash drive to a regular head unit. That is, it is, but USB or SD, often there are no AUX outputs in them! For example, FOLZ can supply you with another radio, but for money, and you will have to pay decently! Guys, I urge all manufacturers to wake up, the 21st century is in the yard, and you take money for functions that will soon be full-time on bicycles! Well, it can't be like that. Okay, this is a cry from the heart, but there will always be justice for such “cunning” manufacturers - it’s called a USB adapter for a radio tape recorder, and I suggest you talk about it today ...

Now, probably, many will think - yes, these Bluetooth adapters have already passed, all this is garbage, because the sound transmitted through such an adapter is simply terrible.

The guys are calm - this is not about Bluetooth, although it is still possible to use it as a "crutch" for the radio. For those who do not know what the nightmare is, a small educational program.

What is bad

I will list it quickly for general understanding:

• It occupies a cigarette lighter, in order to connect other gadgets (radar detector, DVR) you need to buy a splitter, and this is already a “piling up”.

• It does not look very aesthetically pleasing, it is easy to touch it with your hand.
• The main disadvantage is the transmitted sound. You know, it is essentially transmitted over a radio channel, and the quality suffers from this, even if you record to mp3 with a high bitrate (quality), then not such high quality will be played through the speakers - it feels like it was compressed with worse quality.

In general, the bluetooth adapter is a crutch, of course it won’t let you fall asleep, but it won’t allow you to enjoy high-quality sound either. Therefore, this is not our method, we need to look for others.

Other head unit

I also want to write a couple of lines about this. Of course, you can "score" and put another head device with a color display, with USB and SD, navigation, and much more. Moreover, it can be connected to the regular buttons on the steering wheel and control it.

But here's one bad luck - the cost can just go off scale. Personally, I myself also thought about changing my radio and putting it with a color display - but damn it, the price tag floats from 25 to 45,000 rubles! Not a lot, but I still want a budget solution. We dig further.

If the hands are in the right place

You know, there are people who use “YOU” with technology. They understand radio tape recorders - computers can easily solder them, etc. Personally, I had such an experience - when a USB adapter was soldered into the board in the head unit of an old Toyota Corolla, and it was made by hand - then they simply brought it into the glove compartment and used a USB flash drive.

But there is a lot of BUT here:

• It's hard to do it yourself
• Good knowledge of vehicle electrical
• You can burn the board, and, accordingly, the radio, and the cost of even the old factory one will be prohibitive

Again, some “problems” are not our method, so why is there no way out? Quietly he is.

USB adapter

I have no task to advertise any product, and now they are just in bulk. The thing is that everything has already been invented before us. You can install a special adapter in a regular head unit, or rather, in its helmet, which will give you the opportunity to use various outputs, all popular ones (USB, SD, AUX).

How it works

• The most important thing is that you do not need to climb inside the radio, or occupy the cigarette lighter. You just remove your regular device and pull out the cable cable.
• Then you need to insert a special adapter between the connector from the radio and the wire connector, this adapter has an outlet for USB connections adapter.

• You hide the adapter itself anywhere in the cabin, in the glove compartment of the panel, etc. But it seems to me that the glove compartment is 100% suitable for this.
• After that, we install the radio in place.
• Now you have outputs for the flash drive and other devices.

Moreover, the management of tracks from a flash drive, possibly regular buttons on the steering wheel.

Subtleties in the settings

You need to understand that this is a kind of emulation for the radio, it “thinks” that it is reading a CD, but in fact it is USB. So the flash drive must be properly prepared.

To do this, six folders with numbers are created on it, which should be named “CD”. That is, "CD1", "CD2", "CD3", etc. In the seventh folder "CD7" - you can already throw music, only then it will start playing. If these folders do not exist, then playing tracks is not possible!

pros

Needless to say, there are just a lot of them.

• Easy installation, even a girl can handle it.
• Often, old radios can no longer play discs, this happens - because the laser burns out (becomes weak), so long searches for tracks begin to stutter, etc., this will not happen with a flash drive by default.
• Easy to record and play, discs are still almost a one-time thing that still needs to be burned on a computer. I threw it on USB in a few minutes, inserted it into the port and enjoy.
• The purity of the sound, incomparable with Bluetooth, what quality was thrown, and this will be played - just a huge plus.
• Does not take up space in the cigarette lighter.
• You can not change the head unit.

Some pluses, you can breathe life into the old head system. Now, probably, you have a frozen question - the cost, what? If we talk about the price, then it is also tolerable:

Only with USB - about 2000 - 2500 rubles.

With USB, SD and AUX - 2500 - 4000 rubles.

Available for all cars - TOYOTA, FORD, VOLKSWAGEN, MAZDA, etc.

I think 2000 is a normal price, don't go to a pub with friends on Friday and buy it!

The term Bluetooth literally means "blue tooth". given name specialists from Ericsson appropriated the new data transfer protocol in honor of the Scandinavian king Harald the First Gormsson, who, having a blue-toothed smile because of his love for blueberries, was able to unite the peoples of Denmark with the population from the Swedish province of Scania in the 10th century.

General information about the Bluetooth standard

So, the conclusion of this small historical epic is as follows: bluetooth for a car radio is designed to unite, but not nations, but various electronic devices through wireless connection low power. Of course, these devices must support blue tooth technology, and, if necessary, also be equipped with appropriate programs and drivers.

The Viking king could not even dream of such popularity as his nickname won)))
At present, the standard for data transmission using Bluetooth technology has firmly taken its niche in the market due to its simplicity. Well, how else? Just a few simple steps to set up the equipment and the universal bridge between devices is ready, while it also saves the user from a whole bunch of now unnecessary wires.
Well, in addition to this, this radio link can combine several peripherals, which allows the creation of small private groups in addition to common fixed network infrastructures.

Bluetooth in the car

Although the data transfer protocol has recently begun to be used in radio electronics, it has already gained such great popularity that now no one is surprised by the one installed with bluetooth.
What is useful "blue tooth" for a motorist:

• Usage wireless technology data transmission allowed engineers to significantly improve road safety by implementing the “Hands Free” function in bluetooth car radios, which literally means “hands free”. To use this function, the driver uses the radio microphone and the general acoustic system car;

• A more advanced bluetooth car radio allows you to create your own phone book by synchronizing your work with your phone or downloading it directly to your storage device. Although the price of such a radio will be somewhat higher, the convenience of dialing the called subscriber's number from the display of the car radio is much more convenient and faster (see photo).

In addition, with incoming calls, the bluetooth car radio automatically mute or completely turns off the music being played and displays information about the caller. Such devices can receive calls even when turned off.
The real trends in the development and mutual integration of the components of the video and audio systems of the blue tooth head units are gaining more and more opportunities:

• Some with bluetooth can receive and simultaneously process from external sources (phone, DVD player, player, etc.) a stream of information of various formats (music, photo, video);
• The hit of the season at the moment is the bluetooth car diagnostic scanner, which, being placed in the appropriate connector, reads the relevant information and transmits it to the screen of the device synchronized with it (car radio, phone, laptop) in real time.

As you can see, the technology of the "blue tooth" has greatly facilitated the life of a simple motorist, but what about those who have an entire musical car set consisting of a radio combined with a cassette deck? Surprisingly, there is a way out...

Homemade "cassette" Bluetooth

This instruction will once again prove to you that even an antediluvian device can be integrated modern technologies, having available only ardent desire and perseverance . So, in order to get an elegant, do-it-yourself device that allows you to get a wireless bluetooth speaker from an old one, we need wireless sports headphones ...

... and a cassette adapter.

We disassemble the Bluetooth headset

This headset can be disassembled without regret, since the sound quality of Chinese headphones is such that the maximum they are good for is listening to audio books.
The bluetooth headset includes:

• Speakers;
• Lithium-ion accumulator battery;
• The board itself with significant elements soldered on it.

Of all this "wealth" we only need a battery and a motherboard responsible for amplifying the sound, for receiving the Bluetooth signal and controlling the charge of the battery.

Converting the cassette adapter

As you might guess, in the next step we will remake the "offal" of the cassette adapter, which consist of a magnetic head with audio wiring soldered to it, ending with a 3.5 jack connector.

• Keeping a guideline for the pinout of the jack connector, we solder the wires of the left and right speakers to the magnetic head, as well as their common wire;

By the way, the rechargeable battery together with the system board fit freely in the case of the cassette adapter.

• Then all that remains is to make a technical hole in the body of the adapter for recharging the lithium-ion battery, unsolder the old cable with a 3.5 jack connector at the end and fix the board with the battery inside the cassette adapter using instant glue.

If all of the above is done correctly and accurately, then the device is determined by any mobile phones and computers like a wireless speaker.

Examination

We close the lid and proceed to the testing of a freshly baked device:

• We insert our Bluetooth speaker into the cassette connector of the car radio;
• Press the play key;
• We are looking for our headset on the phone / tablet / laptop;
• We start playback of the selected track through it;
• We dance, we laugh

On this article, I consider the article dedicated to car radios with bluetooth to be finished, and I leave the topic open, since I do not exclude that during the writing of this article, the capabilities of Bluetooth have noticeably expanded.

Connecting additional equipment to the car sometimes causes some difficulties.

This is due to the fact that the connectors for connecting can easily be touched and therefore render them unusable. Accordingly, the choice of connected devices should be taken seriously.

There are several ways in which you can organize playback of audio files:

• FM transmitter- a small device that connects to the autoplayer via radio frequency;
• using Bluetooth Flash- in fact, a flash drive that provides a Bluetooth connection;
• via Bluetooth to AUX adapter, powered via USB.

Application

Bluetooth is a technology that is very much in demand for drivers.

In the car, it can be used to communicate via mobile communications without holding the phone to your ear. Moreover, it is prohibited at the legislative level.

Accordingly, communication via Bluetooth still plays an important role in terms of the safety of the driver himself.

Nonetheless, this technology can be used for other tasks.

These include the playback of audio files on the car radio with mobile devices ( , ).

In addition, use this wireless network and to perform simple tasks like transferring photos and tracks between phones.

In addition, Bluetooth technology works great in the car. Here its range is limited only by the interior of the car.

There are no load-bearing walls or anything. The signal must be good. Interference is practically non-existent.

Yes, and devices connected via Bluetooth networks are in close proximity to each other.

Moreover, there are no special rules for the placement of special equipment and adapters. You can even put them in the trunk.

Bluetooth and handsfree

The most popular bluetooth devices are hands free. Moreover, this solution is implemented in several ways.

Personal Bluetooth headset. It is, in fact, a mono headset.

Usually they hang it on only one ear - it doesn't matter if it's right or left. In some models, it is combined with glasses.

However, such a device does not have to be used only in a car. Such a headset simply provides communication with your phone. You can use it both at home and on the street.

In a car, the advantage of this technology is that the driver is not distracted from driving. His hands are not busy. Accordingly, the chances of making an accident are much less.

True, there are several negative points in Hands free devices.

In most cases, you do not know who is calling you. You just understand that they are calling you, and that's it.

True, in some headsets a solution for recognizing the caller is implemented. His name is pronounced in accordance with the way it is written in the address book.

In addition, you still need to dial a subscriber on your smartphone. An exception can be called premium-class models with voice dialing.

When you are playing via Bluetooth and you receive a call, the volume on the radio does not decrease. You have to roll it yourself.

In addition, when buying Hands free, pay for the next moments:

• buttons on a mono headset should be easy to press;
• fastening to the ear must be strong so that the mono headset does not fall out with simple head tilts;
• also check if your phone is compatible with your hands free.

In addition, some models are equipped with a built-in DSP processor. It just increases the intelligibility of the speech signal and has a noise-canceling function.

This device made as a monoblock. It also has a speaker, microphone and control buttons.

Usually it is installed using the cigarette lighter socket and left near it. However, sometimes the device is placed on the sun visor.

The cigarette lighter connection provides uninterrupted access to the car's electrical network.

However, the driver has to lean slightly to accept the call using the buttons. Thus, it is possible not to react in time if a person suddenly runs out onto the roadway.

Thus, the visor-mounted option would be better in terms of security.

Especially since the device is closer, you will hear the interlocutor better and speak a little more familiarly - not in the space around you, but in a certain place.

This arrangement requires additional recharging. In addition, it is also not able to recognize the people who call you.

In general, not everyone likes speakerphones. In fact, it's like the broadcaster of your conversation.

If someone is traveling with you, then he will also be aware of what you are talking about. With a mono headset, it's still somewhat more convenient. But it already depends on the driver.

This connection is made directly to the radio. However, it is not immediately possible to install the adapter correctly.

But the result of such efforts will be justified. Now you can hear the interlocutor on the car's audio system itself.

Music playback becomes smarter - when you make a call, the volume is muted automatically.

In addition, the module is usually equipped with a display. It shows who is calling. You can also enter the caller's number without using the phone itself.

Usually the package includes either a remote control or. So it becomes easy to manage calls.

When choosing an adapter, pay attention to integrated models. They have the most complete functionality.

In addition, they often install the RSAP profile, the so-called remote access to the SIM card.

Thus, the Bluetooth adapter connects to the smartphone's SIM card and copies network settings from it.

In particular, the car takes over the main functions. In the smartphone, it turns off, the screen goes blank and goes into battery saver mode.

For those who are not familiar with this technology, this state of the phone is scary. However, everything is normal, these are the features of this adapter.

Selection rules

So that there are no excesses with the “death of the phone” or damage to the connectors, you need to carefully select it yourself.

Check if the adapter is compatible with your car and the smartphone you want to connect to.

Best of all, when the box of the device itself says that it is compatible with your model. If it says “single-platform model”, then compatibility conflicts are quite real.

In addition, if you do not speak English, see if the device supports Russian and Cyrillic as well. Getting a display exclusively in Chinese threatens with setup problems.

Check the system's ability to display numbers and other subscriber data.

Also, not all devices support voice dialing. Even if it is in the functions, additionally check if it is tied to the intonations of the operator's voice.

In addition to this, the adapter must be able to be updated. Especially, technology is developing quite quickly. And you don’t want to buy a new device every year because the functionality of the old one is not enough.

Not all smartphones also support outdated versions adapters. Accordingly, on this occasion, the system turns into a kind of brick.

Built-in Audio Compatibility

Some vehicles already have an audio system installed, but it does not support wireless technology.

In this case, you are unlikely to change anything. Such audio systems are not subject to modifications. Accordingly, even when buying a car, you need to pay attention to this.

Protection

Authenticating new connections can be annoying, but turning it off is by no means recommended.

Otherwise, you give attackers access to your devices.

For example, you can lose your smartphone phonebook data. And these are just the little things.

Worst of all, when the adapter starts dialing paid numbers on its own, it sends messages with links to virus sites.

Music playback

Bluetooth adapters are multifunctional devices. Thanks to them, you can use not only hands free, but also listen to your favorite playlist from your phone on the car radio.

Some auto players are not equipped with ports or, therefore, bluetooth, then adapters with a special AUX input come to the rescue.

The adapter in this case is connected to the cigarette lighter and directly to the audio input.

In fact, such devices are intermediaries between the audio playback system in the car and the media of the audio files. The price of such devices is more than acceptable. Their range is also quite wide.

With the right approach, this technology can turn your car into the most convenient means of communication and recreation.

Such a device is one of the most stable Bluetooth-based connections in the car.

It is an adapter that uses the analog input of the radio.

The device can also be powered via USB. So it's good to have such a port in the car itself.

Thus, you can connect the adapter both through the cigarette lighter and USB.

Principle of operation

There is nothing difficult in this regard. The device communicates with the audio system through an adapter.

The signal is transmitted via Bluetooth connection to a compatible device.

Advantages

Such a connection has quite many advantages:

• stable signal;
• sound without interruptions and other stuttering;
• compactness;
• high quality when transmitting audio information;
• versatility - works with all radios that have an audio output.

Flaws

Of course, not everything is as perfect as we would like.

The disadvantages of such a connection relate:

• relatively high cost;
• the device constantly occupies the audio input connector of the radio;

General impression

In general, adapters are still the best purchase if you want to communicate with people via the car.

Such a connection is superior to other means of voice transmission. For example, it is constantly connected to the cigarette lighter. You won't be able to enable anything else through it.

The simplest FM transmitters also have a narrow radio frequency range. Some radios may simply interrupt your connection.

Bluetooth Flash is unstable in the transmission signal. The sound from this suffers the most - it disappears or is intermittent. This technology also has a small number of devices that support it.

conclusions

Technology in the car brings more benefits than problems.

Thus, it is better to tinker with installation and connection once, but then be content with all the functions of wireless technologies.

Also, picking up something reasonable is not difficult. It can be a cheap Hands free or an expensive Bluetooth adapter - it all depends on your requirements for the device.

Of course, their functionality is significantly different, but with main function everyone copes - they receive calls, they make it possible to speak without touching the phone.

In addition, some devices help play audio files from other media directly to the car radio.

Thus, you kill two birds with one stone - you can listen to music calmly and can receive calls on the road.

So devices that support bluetooth in the car are already more of a necessity than just an additional feature.

Bluetooth in the car: Which adapter is better to choose

Modern trends encourage the development of wireless methods for connecting any kind of technology. New gadgets come out with a minimum number of connectors, even charging has become wireless. On this wave, I want to get rid of extra wires and cords as much as possible. But what if your car is already several years old, you want to listen to music without cords hanging near the gearbox to the phone, and the radio does not support wireless connection audio devices? A Bluetooth AUX adapter can come to the rescue. In the article we will consider their various options and ways to connect.

What is an adapter?

This gadget is quite simple. It works on the same principle as for smartphones. The only difference is that instead of headphones, there is a plug at its output for connecting to the standard radio connector, designed to supply a linear audio signal. will allow you to get rid of the cable dangling under your arms, and sometimes your feet, save the audio jack of your smartphone and, with proper quality, will in no way affect the width of the frequency range and the pleasantness of the sound.

How to choose the right device

First of all, it is worth checking whether your radio has a connector for supplying a linear signal. If it's not there, don't despair. One of the solutions to this problem will be discussed a little later.

You should decide what sound quality you would like to achieve. If you are a music lover, then you should take a closer look at branded USB Bluetooth Aux devices, for example from Sony, as they have a better audio path. If the presence of music as such is more important to you, but the richness of the sound can be neglected, or the acoustics are simply not capable of producing high-quality sound, and the difference as a result will not be very noticeable, then it makes sense to save money and take an inexpensive adapter of one of the Chinese brands. Its price will turn out to be an order of magnitude lower, but it is worth considering possible problems with signal reception quality.

Does it make sense to take an adapter with an internal battery

Often, Bluetooth AUX adapters in the car are immediately connected to the network through the cigarette lighter socket. But do you need an internal battery in this case? It can be useful in two cases.

The first is to turn off the power at the outlet when the engine starts. On some vehicles, automatic shutdown of all secondary systems is provided in order to redirect all battery power to the starter as much as possible. In addition, such shutdowns are protection against unstable voltage at the time of engine start, which prevents connected devices from failing. But at the same time, the connection with the smartphone will be interrupted, and it will take about a minute to restore it. If this does not suit you, it is better to take an adapter with a battery, even a small one.

The second case in which the battery can be used - no one prevents you from using the Bluetooth AUX audio adapter as a portable headset by plugging headphones into the jack. In this case, when choosing a device, you should be careful that it is not with a built-in plug, but is completed with a male-male cable.

What to do if there is no AUX connector in the radio

Often a similar problem is observed only in old cassette recorders, and even then not for everyone. You can eliminate it with the help of another Chinese gadget, which is a mock-up of a cassette with a magnetic head installed inside, which, in turn, is connected by a cable to the sound source. The principle of operation is to generate magnetic fluxes, and for the read head of the radio tape recorder, this looks like a tape pull. The sound quality is less than a direct connection, but still acceptable, and there will be no problems with connecting a Bluetooth AUX adapter.

If the radio tape recorder is disk, then this method will not work. As a last resort, try looking for the AUX jack on the back of the radio. It is not known for what reason, but some manufacturers have placed it there. If it is not there, then only replacing the radio will help.

How to connect your smartphone to the adapter

Often this question is explained in the instructions for the Bluetooth AUX adapter, but in Chinese versions, the instructions may be only with hieroglyphs or not at all. However, in most cases, the connection is made in the same way. Holding the power button after the indication appears puts the device into a mode in which it is detected by nearby gadgets until one of them is synchronized with it.

If this advice did not help, then it remains only to try to find information on the Russian-language forums by the model code of your adapter. If you are not sure that you can deal with the connection, it is better to choose a model before ordering, on which, according to user reviews, there are no problems with setting up.

Is it possible to use the adapter to talk on the phone

If you want to make your life easier, then one of the best options is to get a Bluetooth AUX adapter with a built-in microphone. Thus, you can free your hands while driving and not be distracted even during urgent calls.

In order for the interlocutor to hear you well, you need to position the adapter so that the microphone is at a short distance from your mouth. If this is not possible, look for a model with an external microphone that can be fixed to the ceiling near the driver's seat.

Conclusion

The Bluetooth AUX adapter is suitable for anyone who wants to get rid of unnecessary wires. But before installing it, you should ask yourself a few questions:

• Does the radio have an AUX input for connecting a linear audio signal?
• Is there a free cigarette lighter socket to plug in the power adapter?
• Will it be necessary to talk through an adapter, and if so, is it possible to place the microphone correctly?
• What sound quality is required as a result?

By answering these questions, you can decide which device and for what price you should buy. Enjoy listening to your favorite tracks while driving!

Have you ever wondered how you can connect your phone to the car via bluetooth through the radio? After all, it is much more convenient to listen to your favorite tracks on the road through a good audio system in a car than through a quiet and low-quality speaker built into a smartphone. And we always carry the phone with us, which means that it can be connected to the standard car radio via Bluetooth and play music through large speakers. It's actually very simple, even if the car doesn't have built-in wireless connectivity. A special Bluetooth AUX audio adapter will help us - a small device that connects to the AUX audio input available on any, even the cheapest car radio. After that, the audio system is able to connect to a phone or any other device that supports Bluetooth wireless technology. Works like with Android smartphones, and the iPhone.

Ways to connect the phone to the car via bluetooth

This article is addressed to those who do not have an infotainment system in the car that supports the Bluetooth wireless standard by default. As a rule, in such a fancy head unit many functions have already been sewn in for managing calls, listening to voice messages, sending SMS, working with the media library, and even playing videos or navigating on the radio screen in the car. At the same time, the controls are usually placed on the steering wheel in the form of buttons, which makes the control of telephone functions even more convenient and safe while driving.

But even if you put the simplest radio in your car with one single AUX headphone jack, you can use most of the above features by connecting your phone via a bluetooth adapter. There are several ways to use it with car radio for the following purposes:

• Play media files from your phone through your car audio system
• Receive phone calls through radio
• Receive audio to any other device that has a 3.5mm jack (Mini Jack)

For the second adapter, to be honest, it is not very suitable. Firstly, the built-in microphone has a low sensitivity and is far from the driver's face, due to which the sound transmission to the subscriber will be very poor quality. Secondly, the sound from the speakers will be transmitted back to the microphone and create an echo effect, which also does not favor adequate communication.

Package contents and appearance of the Bluetooth audio adapter

So, I ordered an audio adapter for a car with Chinese store Aliexpress. The Spartan kit with it also included a short micro USB cable for recharging, an adapter for AUX input and instructions in English.

The audio receiver itself has the following connectors and controls:

• On/Off button
• Micro USB connector for charging cable
• Audio input 3.5
• Microphone
• Light-emitting diode

How to connect a phone to a car radio via a Bluetooth audio adapter via AUX in a car

To connect the phone to the radio, turn on Bluetooth on it and activate the “Visibility” of the phone for other devices.

We insert the adapter itself through the adapter into the AUX audio jack and press the large power button on the device case - the red and blue indicators should flash.

After that, our adapter called DL-Link will appear in the list of devices available for connection on the phone.

Let's connect to it. Next, select as the sound source (“Source”) on the radio “MP3-Link”. This is the AUX jack. After that, you can play music or video - the audio sound will be transmitted through the car speakers from the phone connected to the car via bluetooth.
