I have been trying for a while to buy an OEM CD changer on Ebay to fit my 99 E320 (Fiber Optic). The problem is that I can't find anyone from the MB website down to my local dealer who will tell me what the model number of the unit is that is supposed to fit in the car . None of the sellers on EBay have been able to help me either, they keep saying "any one of my units will fit" and expect me to believe it. If I can find out the correct model # of the unit that is supposed to fit then I can match it with the #s they have. Can anyone help me out, I really suffering without my music Thanx...
