A while back I purchased on ebay an early 90's vintage CD changer for my 93 300E. It is part number 002-820-42-89-90. Although the local parts desk said it was the right one, it is not. Don't know whether it works---the seller said it does.

Question to forum: anyone got an idea who might be able to use this device? I'm inclined to give it free to a good home, but am asking suggestions.

Thanks.
