Need some help on a recent problem. Ever since I got my 96 RM wagon last year (has the factory cassette/CD unit w/Concert Sound II), my CD player acts erratically. It will take a CD in, then it seems to never be able to track it, and gives an Error 20 on the display while at same time, ejects the disc. Sometimes it does play OK, but then starts to skip, miss, and distort, finally does the error code. The owners manual and FSM say to let the unit cool down, and then try to play the CD again later. This does no good w/my unit. Anyone have similar issues?
