I did the aux input install that's on here: GMTNation - $3.00 Aux input via XM interface and I am having some problems with a humming noise that comes at times. I was expecting to hear some of the XM to come through, but this isn't quite the same. It's louder and gets louder when I accelerate. I have read similar articles on a google search and other people are saying it's a bad ground, but I have removed my first install from where I soldered the wires back together, and installed it again using butt connectors and the problem still remains. It usually happens after I've had it going for about 10-15 minutes, but like I said, it doesn't happen everytime, probably half. Anybody have a solution to fixing this? The mod is going to have go if I can't get it right, it's that annoying Also, if I happen to redo some wiring again, I'm going to need a new harness because I'm running out of wire on the one now. I'm not having any luck finding one, only the T-Harness. The part number it has on it shows up nothing. It's called a Factory SDAR Interface Cable for the SIR-GM1.
