Hi:

I have both the 3 pin and the six pin connectors. The unit was purchased at Best Buy a few months ago and was used in my 2003 525i until last week.

I installed it into my 2004 X5 this morning using the 3 pin and the 6 pin connectors. I remember when I installed the unit into the 525i, I had a hissing sound and somehow, Tom, you responded to me and e-mailed me directions on switching the location of a black wire. But, I think that wire was part of the car's wiring and not the IceLink. If it was the IceLink, then that may be the problem.

I cannot find any coaxial cable in that location at all. I dug around back there and under there and found nothing.

I want to thank you for your help with this. I really love the Ice Link and want to get it working!

I see no evidence that there was a cd changer installed in the car previously.
