Thanks guys! The schematics are helpful, and I have been putting off a proper re-wiring of the radio but I suppose it is inevitable. I think Best Buy did the install for the previous owner so that probably explains a lot.

Bronco, I see you have your Axxess grounded into your main ground but I read on the Axxess instructions that that can cause programming issues in certain cases. Perhaps I could also try tacking that wire to some metal in the radio compartment. Do you have the newer USB firmware upgrade version of the ASWC?
