Wiring Diagram for the CD changer harness
 

I bought my X5 3.0i with the ipod adaptor already installed. I purchased a bluetooth adaptor to stream music that plugs into the CD changer plugs. From what I can tell who ever installed the Ipod Adaptor spliced into the clips that go out to the cd changer making those plugs in trunk not work anymore. I have been searching around trying to find which plugs need to be taken out and which ones go back in to the harness and which wire in which plug..

Any help would be awesome. I hope I explained that well enough if not I can try to get pictures or somethingl

CD changer has a 3-pin connector, (+), (-) and i-bus, and a 6-pin connector (or, as an alternative, a coax connector for digital out) for audio, which has only left and right channels... most aftermarket devices mimic CD changer to fool the system to think changer is connected (telegram on i-bus, on the 3-pin connector), and the radio pipes the sound from the 6-pin connector (or coax plug) into the system...

from your description it is hard to figure out what you have and what you want to do - start with the month/year of your ride, then tell us if you have factory nav or not, and if you have DSP or not...
