I'm ordering a new '00 2.8 and I have a 6 CD changer left over from my 1.9 that I'm returning. Anyone know if you can add it to the trunk if you opt for the in dash CD? BMW doesn't seem to know if the wiring will work? I'd like to throw in a single up front without having to pull over to go to the trunk. Sure can't use the rape player. Thanks.
