Hello all, I'm a new ower of a 2007 Monte Carlo SS. Great Car!! I need some assistance on how to connect the proper wire for steering wheel controls to the OEM Nav unit I have. The Nav unit is a Concept T-GM70, and yes I have called Concept for help but they are clueless. Anyway, I have put the nav in a few times and it does work, using the Axxess GM Lan02 interface. The issue is the Axxess ASWC, I have followed the directions connecting the wires indicated: Control Wire 1 Wire ColorDARK GREEN/WHITEControl Wire 1 Polarity(DATA)Control Wire 1 LocationRADIO HARNESSControl Wire 1 Pin #13

GM pin 14 wiring instructions:

The ASWC also has a male/female type of plug but really does not say much on it. The nav unit does support steering wheel control and also states using the Axxess ASWC.

Maybe a different SWC like PAC?
Any help would be great, Thanks!
Tom
