trouble installing oem cd changer in 2003 x5
I have a 2003 bmw x5 w/dsp and navigation. I purchased a cd changer and attempted to connect it. I connected the 3pin cable and the single coax cable to the cd changer but there is no sound coming out of the vehicle. There is no 6 pin connector in my x5 as i looked for a while. There is no sound coming out from the speakers.
Can somebody please help me on this. I can go through the tracks and the titles appear on the navigation screen but there is no music coming out from speakers.
