Good day to you!

It’s a widespread problem; in most cases, it is common for conventional car stereos, made in 2015 and earlier. Old mp3 players in these stereos cannot read flash drives, formatted in NTFS file system. If you’ve bought a new flash drive, most probably, the system it has been formatted in is NTFS. Modern Windows versions also on default offer to format flash drives in NTFS.

What to do? Everything is quite simple! You should format the flash drive in FAT32 file system and you’ll have no problems with reading it in your car stereo!

If the size of your flash drive is less than 8 gigabytes, you can follow our instructions to format it (link), the only difference – you should select FAT32 file system:

You should select FAT32 file system

If you have a flash drive of a larger size – the standard formatting program in Windows won’t even offer you to select FAT32 filing system, and you will have to use a special program, which we will discuss further.

A car stereo fails to read a flash drive:

1. Download a special program GUIFORMAT32 (Download from the server  | the author’s site). It’s a simple program that contains no viruses or malicious software and requires no installation. Before downloading it to server, I’ve checked it for viruses. 

2. Start the downloaded program; you will see this window:

3. Select your flash drive out of the given devices (you can find its letter in “My Computer” section), type in the name you like (you can skip this step) and click “Start”. That’s all! 
Now you can record your favorite music on this flash drive, and your car stereo will easily read it!

Good luck to you! If you have left any questions – don’t hesitate to ask!

Worked like a charm! Thanks.
I tried this but it doesnt appear to work -
I had the Flash Drive using it with my car stereo, I decided to put more music on it and downloaded FAT32 Format as you said above to format the drive before putting new music on it. Now I get "Read Error" when putting the flash drive into the car - it was working prior to formatting. I deleted the songs I put on it and put the original songs that were on it back on however I still get Read Error - my only guess is that GUIFORMAT32 has corrupted the drive but it works in a PC so I am not sure.
Just in case anyone is having the same issue; the flash-drive formating worked for me and my car just perfectly.
BTW, I formatted a 18GB flash drive even without downloading the GUIFORMAT32 program and it did the charm anyway so if you're having the same problem just give it a try.
I tried the above explained steps on 64GB Sandisk Ultra fit and got success. Before this I was facing error 2 in car stereo.

Thanks :)
i followed your instructions regarding my usb flash drive can not play in car stereo but same it can not played
