cdrw

Hi there should the factory changer in a 2002 c class with command be able to play cd rw ? I made a cd from iTunes ( in audio format not mp3) and it won't read it as even being a cd in the slot, I'm making cd s as my fm modulator gets feedback from various functions and sounds rubbish ...

Does anyones Audio 10 CD play CDR's or CDRW's? I do not seem to be able to play these in mine, does anyone else have this problem or know a solution?
