Dear Listeners, I am having conflicting arguments about installing an aftermarket CD Changer in my 1996 328. My BMW dealer of course says this is not possible. My car stereo store tells me no problem. Questions are: Can I install an aftermarket Alpine CD Changer with the stock stereo that came in my 328? If so, which model will work, and if not, am I stuck going to my dealer and paying a major premium? Thank you Brian
