I have the same error happening with my clarion 6 disc change - cdac er2 error - history of the unit is that the magazine has been stuck before and I've had to take it apart to get the magazine out - this has happened probably 2 times - and each time I remove the magazine, the unit started working for a while until the cdac er2 came back. Now the error is happening w/out the magazine being stuck - anyway sorry I don't have an answer to why its happening but wanted to share the same error issue. Thanks, SB
