How do I reset radio on '99 CLK 320? I'm getting a Code CJ.

Thanks! I DID have the battery unplugged at one point, so I read that part in the booklet. I've done what they said; however, I didn't find my booklet until AFTER I had punched in what I thought was the code. Naturally, it was wrong and I'm at the WAIT stage now 'cause I entered wrong code more than 3 times. I found the correct code, but I can't get past "Wait." It say radio will be locked for about 10 minutes, with the radio left "on." Well, no, "Wait." won't go off. Do you think I should start all over - - - - unplug battery, etc. Thanks for your thoughts!!

you could try that,should work.
