I have been having an issue with my Axxess AWSC. After I got it installed it seemed to be working great, all buttons worked, etc. I then noticed my stereo was randomly changing the Source to the next one. Like I was pressing the Source on the steering wheel. Volume up and down too. Happens like 1-2 times a day. I thought it was definately a wiring problem as I had some concerns with tapping into the car harness (used the wire taps for the 3 wires). I decided to wire it up better by using another Scosche stereo harness to use some of the wires and I installed them on my wiring harness for these 3 wires. Install went ok and I was hoping this would fix the issue. Nope. Happened once again on the way to work today.
I also found this intersting thread on another site:

Looks like I may have to try updating the firmware next.
