When these things break, it's often a big pain. Maybe try the Mercedes Benz forums in case it's a common problem that enthusiasts know how to fix themselves--in most cases, you need a stereo specialist to help you out. An aftermarket specialist can potentially save some money over the dealership.

Its somewhat of a common problem with these for some reason... there is a spring mounted wire that somehow gets stuck. If you can locate it by taking the CD holder out, you can unhook it and will work fine for a few months more, then it will do it again, and again...lol. Hope this helps...
