I have an 07 GT with the 6-disk Monsoon. I thougth these were capable of playing MP3 disks. I put one MP3 on a disk for a test and nothing played. I put the same disk into my friends Hyundai that plays MP3 and there is no problem. So two questions.

Should my car be able to play MP3s? The owners manual seems to indicate MP3's should play.

Is there some kind of folder structure needed on the disk?

Thanks.
