Need to wire a hands free phone kit into the AV.  Anybody have the wiring information for the 2004 Avalanche with Onstar and Bose stereo plus rear seat controls?

 I am trying to install the "Mute" wire to the stereo so it will work like the OnStar system when I get a call, it mutes the radio and I don't have to.  Any help would be appreciated.

If I remember correctly the On Star is integrated into the stock radio via the class II Data Bus and its muted via that data bus....so If I'm correct then there is no "mute" wire behind the radio.   And I'm 99% sure that is the case.
