Onstar Mic

[Flashy2003]

Im putting a blue tooth kit in my after market head unit. 2007 Nbs silverado. Does anyone know if I can tap into my Onstar microphone and use it instead of the mic that came with the kit? And is the Onstar mic in the head liner on my left or in the head liner console with the lights?

It looks good but still doesn't tell me if I can use the onstar mic. I have an after market head unit so the sound will already go through the speakers. I just don't want the ugly mic hanging around my truck.

You'll need to use the mic from your BT kit.

Does anyone know were I can get wireing diagrams for my onstar or truck in general? 07 Silverado nbs
