I have a 1995 325is, and well i just purchased a cd changer model number 82 11 1 469 404 and was told by my bmw dealer that it would be compatible. I got the changer today and well it doens't seem to be compatible unless theres something else i should know. what is there to do, any adapter? I don't have the I-Bus and apparently this changer is for an I-Bus connection.
