I bought a used 06 Equinox 2 days ago and for the life of me i can not get it to play MP3's. It says mp3 on the radio so i know its suppose to play them. I stick the cd in and after a few seconds it pops it out and says 'check cd'. i've tried to burn 2 different cd's and they both do the same thing. i have windows vista and have just been using the built in cd burner in vista to burn them. the cd player does work, i can play regular cds in it just fine. any ideas would be greatly appreciated!!

Look up your menu and find out what the bit-rate you have to burn your MP3 CD with. Also can you play your MP3 CD on other non-computer MP3 player(s)?
