2 Trouble with formats
2.1 Formatting

Car radios with mp4 format are especially popular today

The video format for a car radio matters; if the radio, for example, does not read MP-4, then you have big problems, the largest number of videos are released in this format. Modern car radios support a wide range of video and audio formats, but when we insert a flash drive, the files cannot be read, since it is necessary to take into account what format of the flash drive the car radio reads.

Can I watch videos through AUX?

That is, using AUX

,
you can
connect an external device to your TV or any other audio system and listen to music from it.
The name AUX
comes from the English word Auxilary.

Existing formats for radio tape recorders

There are many formats (so-called sizes, further in the text), some are more in demand today and are used in a wide range of models, others are less common, either outdated or too new:

The most famous audio sizes are MP3, WAV, WMA, CDA
MP3 is today the most popular and most licensed format for storing audio data, which was developed by a group of MPEG campaign specialists
In this size, a new algorithm for encoding information with losses in the upper and lower frequencies of sound is used

Note: There are no such losses in the CDA format.

But the technology allows you to significantly (10 or even more times) reduce the size of an MP3 file in comparison with the original CDA format
Moreover, the average bitrate of a compressed file is more than 128 kbps
And the higher the speed of information transmission, the better the quality of the resulting music file is reproduced
However, due to the use of the perceptual encoding method, the deterioration in quality during playback remains practically unnoticeable to the average listener

Note: You can only notice the difference if you have a good radio and excellent branded headphones, which 90 percent of ordinary listeners do not have.

CDA has been used for a long time on CDs, it is the very first and simplest for storing digital audio data. File playback occurs at a certain fixed disk rotation speed and has the highest playback quality, this is explained simply, data in the CDA format is not compressed, don't give in to him
WAV is the closest size to CDA in terms of its internal content
The format is “outdated”, so it is rarely supported by modern car radios
It has a rather low quality of reproduced sound and a large file size
WMA is a format developed by Microsoft Corporation and is used for playing and storing audio data.
In fact, it is an alternative size to MP3
A distinctive feature from other audio sizes is the highest encoding rates (compression and surround sound and voice), this allows you to get files of a fairly small size
The format uses the Lossless method, which allows you to maintain the quality of all encoded data
The disadvantage is the low threshold of its sensitivity to errors
If data is damaged, then it will be impossible to reproduce it not only in the area of damage, but also 5-10 seconds before the damage and the same amount after that
AAC - some car radios today support this format, the m4a file extension (meaning a file without any protection)
The main feature is the lower quality loss that occurs during compression compared to similar MP3 sizes
It is used much less frequently than other similar formats (like MP3, WMA)
There are a number of formats that are practically not supported by car radios.
These are outdated formats for lossless information compression - WV, ALAC, MLP, Monkey`s Audio APE, TTA
They occupy large amounts of data and are used in acoustic systems of recording studios, in high-quality sound reproduction equipment and specific sound devices.
The only exception to the rule is the FLAC size.
At the moment, this is one of the audio codecs still supported in car radios that uses the Lossless recording method.
A distinctive characteristic from similar formats is that information from the audio stream is not deleted and remains in its original form after it is compressed.

Today, disc car radios usually support all the classic sizes for video playback:

Video format for car radios - VCD, DVD, and SVCD
Used to store video with sound
All of these formats have some limitations when choosing the size and proportions of the image that is encoded in them
The most popular video format used in DVD car radios (see DVD car radios with a screen and their review) is MPEG4 (with Xvid, DivX, and 3ivX codecs)
This allows you to view video files with a high level of encoding (compression)
It is designed for low data flow, it provides high quality sound and image, and has an excellent ratio of size and quality of playback of file contents
MP5 (aka MPEG5) is one of the modern multifunctional formats; it combines the capabilities of its other predecessors, such as MP3 (aka MPEG1) and MP4 (aka MPEG4)
However, MP5 significantly expands its capabilities
This size is capable of storing and then reproducing information of any nature (images, audio, and video), while simultaneously performing automatic decoding of information
This is explained by the fact that a huge number of various combinations of codecs and media containers were initially built into it.
In addition, this format can use multi-codecs that are a priori suitable for any format
MP5 can provide the highest quality audio and video playback
It is supported only by expensive and modern car radios with high screen resolution
But support for DVD recorders for HD codecs (such as H.261 - H.264) is very rare
The reason for this lies in the low resolution of car radio screens (up to 800*480px, it’s simply not enough)
RM, RAM, and RMVB are formats for media files that were developed by the RealNetworksProducts and Services campaign.
They have the lowest quality of the reproduced image compared to the others, but have excellent speech intelligibility even at low video bit rates
They are distinguished by the extremely small size of the resulting files
AVI - the format was first used by Microsoft Corporation
The size can accommodate combinations of audio and video data, provided that codec compression is used
What allows you to play video and sound simultaneously
Combinations of codecs can be used (for example: MPEG4 - for video and MP3 - for audio, or DivX - for video and WMA - for audio)
To summarize, we can confidently say that all modern car radios are capable of reproducing all major video and audio formats for digital encoding
Each of them has its own positive and negative properties. Therefore, even a demanding buyer will be able to choose a radio that will satisfy his requirements and will play files of the required size specifically for him
As a last resort, there is always the possibility of converting formats on a computer using special converter programs, which will be very difficult to find on the Internet
To the question what format is in cd car radios, I answer CDA and MP3, in old ones only CDA, so it is recommended to purchase modern ones with a large number of playable sizes

Recording process

The process can be carried out using built-in Windows tools or third-party programs. If you have Windows 7, 8, 8.1 or 10 installed on your computer, everything is simple, you can work with almost any format. If Windows XP, you will have to install special programs, since in this system the built-in recording tool has low functionality .

The most popular programs are Ashampoo Burning Studio, Astonsoft DeepBurner, Free Easy CD DVD Burner, Nero Burning ROM. Don't worry, the principle of operation is approximately the same in all of them:

Burn Audio CD using Nero Burning ROM. On the left are the files on your computer, on the right are those that are already on the disk

When you launch the program, several options will appear in front of you, among which will be “Create Audio CD”, “Create MP3 disc” or something similar. Select the desired option.
The next window usually asks you to give the disk a name. It must not contain spaces or Cyrillic characters.
Then you need to select the drive in which the recording will be made. Not sure what to choose? Click the Computer icon on your desktop, Start menu, or simply File Explorer. Find your drive in it and see what letter it is designated by.
You will be prompted to specify the files that will be written to the disk. This can be done by selecting them on your computer and clicking the “Add” button, or simply dragging the desired tracks into a special field. There is usually a scale at the bottom that shows how much free space is left on the media.
In some programs you can select the recording speed. The lower it is, the less likely it is to make an error, but the process will take longer. For maximum quality, it is recommended to choose options 1x-2x. The option “Copy all data to an image on the computer’s hard drive” will slow down the recording even more, but will almost completely eliminate the possibility of errors. By selecting “Create a multi-session disc”, you will be able to add new files to the media in the future, but this will speed up its wear and tear.
That's it, all you have to do is click the “Start Burning” or “Burn Disc” button, and the process will begin!

Multimedia system Pioneer AVH-X4800DVD 2DIN

The company knows how to make surprises. This time, fans of spectacular sound have waited for a new release of a car radio model with unlimited multimedia functionality, and the head unit itself is equipped with a 7-inch sensor and has the latest Pioneer AVH-X4800DVD 2DIN multisystem.

This type of player is easy to operate and has an increased response speed. All commands are executed with one touch. The entire system supports an unlimited number of formats.

As we see, these are the most popular formats. Also, the Pioneer multimedia system has a completely new format according to the FLAC standard.

Note. All of the above formats have improved sound quality. Considering their past generation.

The car radio has a positive aspect. Here you can listen to music on car audio, which has the purest sound. All rights are given by local connection of acoustics to a subwoofer with rear front AC. Previously, only Pioneer models, which were among the top three, had this function. So, each channel will be redirected through a separate amplifier, this allows for even better sound reproduction.

The model is also equipped with an excellent built-in radio receiver, where it can store 24 radio waves in its memory.

Trouble with formats

Almost all modern radios are equipped with USB outputs for connecting portable devices:

The main devices, of course, are USB Flash or, popularly, “flash drives,” on which today it is very convenient to store music and then play it in the car
In addition, today you can connect an MP3 player, phone or portable hard drive via USB, and 50% of car radios will also read these devices
Why only 50%, because, as a rule, the radio is designed exclusively for FLASH, a hard drive, or a phone may simply not be detected
It’s convenient, you download music through the “computer” and in just a couple of minutes you listen to it in your car
Got tired of it, erased the old recordings with my own hands and immediately recorded new tracks, no need for any discs, which then gather dust in bundles
However, sometimes problems arise, the “flash drive” in the radio is not readable, although everything was fine on the computer
This happens, but it does not always mean that your “carrier” is broken
The most common option is too much flash memory
Typically, the manufacturer itself provides instructions for the radio, which indicate the maximum volume of media that your radio can recognize and play.
Typically, the maximum volume is 4 Gigabytes, for outdated options it can be 3 Gigabytes
And if you insert 8-16 gigabytes, then the radio simply does not perceive it
Accordingly, this flash drive will not be read
The second option is the wrong file system of the flash drive.
The format of a flash drive for a car radio is FAT32. Modern high-speed flash drives have other file systems, for example, NTFS, so it will not be readable
Here you need to look at the file system on your computer
To do this, simply insert the flash drive and right-click - then select properties and look for an item called “file system”, it should be FAT32
If you have a different one, no problem, just below we’ll look at how to reformat a flash drive
If the flash drive has the correct system and file format, and yesterday the music played without problems, but today it doesn’t, this also happens
Moreover, when you insert a “flash drive” into your computer, it sees everything and plays the files, but the car’s radio refuses to play music
It's simple, errors could have accumulated in the flash drive itself
You just need to format it, I’ll tell you in detail how to do this below.

Attention: After formatting, all data will be lost, so if possible, copy it to your computer

When your “Flash Drive” is not readable both in your car and in your computer, but is recognized by the computer as a removable disk
There is only one solution - format
However, the files will no longer be saved, you will no longer be able to rewrite them - because the flash drive is unreadable
Music is not a big loss, you can re-upload it from your computer or download it from the Internet
When the device is not readable either in the car or on the computer
The computer usually writes - device detected is not recognized, the problem repeats on different computers (it’s better to check on at least three)
It looks like the flash drive is dead, all you can do is buy a new one, it cannot be repaired
If suddenly on any computer it is suddenly recognized as a removable disk, read on
The cause of the breakdown is either a defect, or this is the price of the issue for careless handling, before removing the flash drive from the radio, it is better to turn off the radio itself, the same thing when turning it on
On the computer, first select the option to safely disconnect the device, then you can remove the flash drive, otherwise there is a possibility of damage to it
I don’t even want to argue, you don’t need to prove to me that you took it out and put it in a thousand times, without following the described measures, and everything was fine - the thousand first time it may not work

How to connect a flash drive to a car radio

If there is no special connector for USB, then the flash drive can be connected to the radio in other ways.

Modulator

This is a listening device that transmits signals from a flash drive over a radio channel. It must be connected via the cigarette lighter. We'll have to modify the radio a little.

Connection instructions:

Disassemble the radio and disconnect the player.
Disassemble the modulator and remove the microcircuit.
Solder the plus from the modulator to the plus in the radio. Do the same with the negative cable.
USB output to the front panel.

Next, you need to connect the audio output of the modulator and the input of the car radio with a wire. This device is suitable for playing in a car.

USB adapter

This is a device for connecting a flash drive. It is connected to the audio outputs of the radio.

Installation is as follows:

Pull out the car radio.
Connect the wire from the adapter to the corresponding connector on the radio.
Connect the adapter to the other end.

If necessary, you can connect the adapter to the glove compartment or another place where it will not interfere with driving the vehicle.

Adapter

For this type of connection, you need to make modifications for a flash drive.

The whole procedure boils down to the following:

You need to take the wire from the headphones and remove the insulating layer. The green and red wires will be visible. These are the left and right channels. The headphones need to be cut. Clean the conductors and solder them to the tulip-type connector.
Secure the main cable braid to the base of the tulip.
An adapter must be connected to the output for the external signal of the radio. And you can already connect the media to it.

In the end, all that remains is to activate the AUX function.

Via AUX

If there is no AUX connector, then the flash drive is connected to the standard radio.

Why so many difficulties?

The Fat32 format has a number of disadvantages. One of them does not allow a flash drive to supplant the computer’s boot disk, eliminating disks from use once and for all - this format is not designed for recording, storing and transmitting a large amount of information. For example, this is what prevents the computer’s operating system from being written to the media, and a disk drive in the computer is still needed. The largest file that can be written to a flash drive in Fat32 format is 4 gigabytes. Besides it, there are other formats: exFat, NTFS and others. The user is invited to independently choose which format is better and which one is needed. Having found out the format that the radio tape recorder assumes, or simply deciding to find the one you need, you can safely start formatting.

What to check first:

The first thing you need to do is check whether the information from the flash drive is readable on another device - another radio, computer, laptop, etc. If the computer does not see it, then the problem is clearly not in the car's stereo.
Check the USB socket where the data storage device is inserted. This can be done by inserting other flash devices. If the stereo system does not read these devices, then there may be a bad contact in the connector itself, but if the information is read, then the problem is probably not a broken connector.

In the case where these mechanical damages are absent, it is worth paying attention to some other aspects.

Criterias of choice

The choice of device should be based on the nature of its use. Its characteristics, installation location, required additional functions, etc. will depend on the tasks of the device. There are several main purposes for motorists when purchasing a car TV:

The next important selection criterion is the installation location. It depends on who will be the main viewer and for what tasks a TV tuner is needed. For example, for cartoons and children's games, a mounted, built-in headrest or ceiling-mounted car TV is enough to keep a child occupied. To work with the Internet, the passenger in front needs a monitor on the dashboard on his side. For the driver to watch movies and TV shows - on the dashboard, in the rearview mirror or sun visor, to control parking and record the recorder - on the dashboard or panel.

Pay attention not only to the price, but also to the screen parameters and antenna quality. A bad screen on which you can’t see anything in the sun, with a grainy image, that doesn’t read half of the required formats, and that requires point-blank viewing due to a small angle, will be a waste of money. A bad standard antenna will require the purchase of a remote receiver with an amplifier.

Look for models with a USB connector; it’s most convenient to watch movies and videos from a flash drive. The ideal option is a receiver with the Internet, but then you need to take care of access to it. If your budget allows, you can equip the cabin with several TVs and combine them into a network so that all passengers can watch one movie or work with the monitor separately.

Trust companies that have proven themselves in the global market. The chance that Prology or AVEL will fail is less than that of an unknown Chinese brand. It is better to start shopping on marketplaces like Aliexpress after carefully studying the reviews, seller ratings, return policy and money.

When reading reviews, studying videos with reviews and articles with ratings of models, remember that you need to pay attention to the facts, follow the technical characteristics, remember that they often don’t write about the good - they just use it, but write about the bad. Therefore, it is necessary to filter information and separate emotions from objective data.

How to fill it?

First you need to get it, but it is installed via a flash drive

What's the point if there's no video?

It makes sense to wait for the new standard software for those who have problems with the rear view camera not turning on. And about the video, if only the Kulibins can come up with something.

Hello. Tell me where to get updates?

Friends, tell me who has a 340 radio, or better yet, check if there is an option in the screen settings to turn off the screen after 10 seconds! You check the box and it works, but it works until you remove the key from the ignition, you have to set it again, and so on every time! Is everyone like this? Check it out! And the second question is where to look for updates for it? At OD?
