Although I probably have an Axxess ASWC sitting at my doorstep right now from Amazon, I just purchased the 20-pin harness w/ SWC wires and another Axxess ASWC from svxDC (guaranteed to have the latest firmware). I also expect to have the AVH-P3400 hitting my doorstep any day now from Crutchfield, however that will also be making its way back to sender, as I've officially decided to go with the AVH-P4400
I'm sadly having a late night at the office right now, but I will hopefully be picking up my Metra 95-8902 dash kit after I leave work and then I think I should be in a holding pattern until all proper items make their way to my door! Time to sit back and relax
slowhat - I've heard the BT steering wheel buttons are sometimes off with the auto setup. Let me know if anything changes through your research/playing with config options.
