Hey...Sarah is Back!
Best answer from Reap3r.
It only shows FAT and I cant change to MP3
Lolz. FAT is a filesystem. You don't need to change that. Are you trying to put mp3 files on the drive?
I have a new car with a usb. I have put music on to a memory stick but when I try to play it comes up FORMAt all the time.I just don't know what to do (sell the car!!!!)
Maybe you need to make a folder called "music" on the drive for the stereo to read it, and make sure the music you drag onto it are all .mp3 formats.
