Hi all,
The head unit that came with my car was a Panasonic MRX777 (CD and mini disc in single din unit - http://www.minidisc.org/part_Panasonic_CQ-MRX777.html).
The whole thing lights up fine, playes radio stations etc, but when I insert a CD or a mini disc, it whirs for a bit, then says "E1" (disc error), ejects the CD and shuts down.
Anyone have any ideas??????????
