300M stereo unit

I have a chyrlser 300m (2002). Does anybody know why I cannot play copied CD's, or downloaded CD's on the unit. When I insert the CD, ERR flashes on the panel. This is a new enough car, one would think it can read these type of CD's. I would appreciate any insight.

you probably have to find the brand of AUDIO cd that work. I changed my entire system (i have a 99') but i remember that copied cd's worked on the factory deck. Try sony audio cdr's.
