I was looking for an inexpensive CD changer cartridge since my CD changer cartridge was replaced with one from a lexus that wasnt correct. I couldn’t find a used one that was reasonably priced. Most were $80 or more.

then I noticed one from from Mercedes looked the same. So I bought it ($28) and yup, it is same as 06 STR and others that use that changer.

here ya go. Mercedes Benz 6 CD Holder Changer Magazine Cartridge A0028206289 OEM
