I think is a cd issuse..i had a 07 rental that would play one burned cd, but it would play tha other..they where tha same brand..it just would play tha other...it was a base gp. It could be a certain brand of cd that it will only play. i had a 04 stratus that would only play a certain type in tha factory head unit. the ones i used are maxell cr-r 80 min./700ms..
