I just installed my new kenwood ddx7017 and for some reason it wont play mp3s off of cds. It reads the cd and the head unit shows it playing, with the time counting down, but there is no sound. CDs and DVDs work just fine. Also, it says "CD DVD" on the top, when my 7015 used to say "CD DVD MP3/WMA".

what do you think is going on? I know it supports mp3 and I have tried other discs.
