No, the US Telematics can only mute the head unit. If you want more integration you would need to get the OEM BT phone interface (which may or may not work together with OnStar).
BTW, can you take a look to see who makes the cable going from the phone to the connector below the center armrest? Of if there is any number on that plug? I'm planning on using the GSM antenna and power from the phone prep but I don't want to by that $300 kit just to get the plug and cable.
Thanks,
Dirk
