2007 Volvo S40, 1991 Mercedes-Benz 300E
I know this question has been asked a million times, but I can't seem to find the exact information that I am looking for. I am wanting to buy a used CD changer for my 2001 E320, but I am not sure which model is compatible with my car. In one post I read that the A002-820-7989(MC3198) model is compatible and in other post it says that the A203-820-9089(MC3010). Are they both compatible with my car or is one better than the other? Can someone please help me solve this probelm so that I do not end up making a costly mistake and having a CD changer that does not work. Also what is the difference between the two models, they both seem to be fiber optic models? Thanks.
