02 Bonneville CD Changer

Does anyone have the trunk mounted CD changer from the 02 model year? If so can you port some pictures of the wiring and mounting as well as the head unit? There are two options we do not have in our Bonne' ... the bright wheels and the trunk mounted CD changer (yes we even have the engine heater!)...the later I was thinking about adding but have concerns about the head unit (do I have a compatable unit) and the wiring (is it already there or will I have to get the wire and run it myself). What I do not want is an aftermarket unit that uses RF to transmit signals to am FM channel...we had one of those before and we really want to retain the stock options as well as the ability to use the steering wheel controls...


Thanks
