I'm getting close to just lighting a match and letting go....
My car came with the base crap stereo. I am in the process of installing a pioneer 8000BT head unit, with an amp, and new speakers. Everything is in place, almost ready to begin putting the car back together. But I can't get my steering wheel controls to work. I have the AXXESS ASWC unit. It auto detects according to the LED, but the controls do not work. I think I have it wired wrong, but every time I read and reread the instructions, it is correct. I'm guessing the instructions are off. Does anybody remember what wires they tapped in to where? I have searched the forum, and found some info, but no one goes in to detail about wire locations or colors. Should I be splicing in to the factory wiring or in to the wiring in the GM LAN adapter? I have tried searching google, the AXXESS website and crutchfield with no luck. I don't really use the SWC much, but I don't want to have to explain to the next buyer that I was too lazy to wire in an adapter.
As it is right now, the volume will automatically climb to 100% when playing a CD. No idea why. If I disconnect the adapter, the rest of the system works perfectly. Any help is appreciated.
