OnStar, Bluetooth Conversion
I have a new 2009 G6 Convertable with a factory stock CD/radio system, XM and of course OnStar. I really want to know how I can hack into the OnStar wiring to install a bluetooth radio in order to use my standard AT&T cell phone through the sound system and take advantage of the built in microphone. This should not be rock science, but it seems every blog I read makes it appear to be difficult at best. Is there a wiring diagram and a harness available yet to splice into the circuits to install bluetooth. Please advise as I am sure there are some very talented experts on this forum.
