Hoping someone can help me out on this--thinking about picking up a motorola Bluetooth hands free kit, and I want to integrate it with the onstar system--I don't care if by doing this, it disables onstar. Frankly, it's pretty much worthless to me. Does anyone have the onstar box wiring diagram?

What I mean by integrate is I want to use the microphone under the mirror, the radio mute and speaker(s) that Onstar broadcasts out of, and...that's just about all.

Also, for the expert/pro-radio installers out there, how does the auto mute feature work when onstar, or the navi kicks in? Does it complete a circuit (some sort of a signal wire,) or?

If I'm successful, I'll do a detailed write up!

 

anyone?
