Have you considered the MB radio with the built in CD player? It also works the CD Changer. I have the MB Audio 10 CD in my car and it sounds great and it works the factory CD changer. You can get them from Autoclass.net or if you want it for half that, go to German ebay (ebay.de) and search for Audio 10 CD. Of course you will lose the cassette but I've learned to live without 8-Track tapes or cassettes.
