Well ... that didn't do anything. All of the white/tan wires match up with one another, coming from the main harness

I tried hooking up the CD Changer to the Sirius CD Extension cable and there is no whine and longer. So it would appear that my Sirius receiver is the source of the noise.

Bad ground inside the unit? It seems like it was made in May of 2005, would it still be in warranty? How could I have this taken care of?
