Hey everyone! 1st post here, so lemme start by saying what I have. 2007 Pontiac G6 GTP - Avic-Z2, ND-BT1, CD-IB100II, GEX-P10XMT, ND-BC2. None of it is installed yet... Waiting in the boxes they shipped in. I need to work out some design implementation kinks first. I read just about every post I could find on the SWI-PS & CD-SR1. My concern is for the SWI-PS, I have 5 buttons on my steering wheel already Vol, Trk, & CD Change (built-in6cd), so the only thing I would want changed is that into a "Mode' button. But is the only thing this doesn't do is control the BlueTooth/Phone function
