Your best bet here is to contact demon8 designs.
Keep in mind that many of the us spec Pontiac g8s do not have factory Bluetooth.
(i.e. Pontiac guys are using aftermarket solutions for Bluetooth), hence the reason why the plug may or may not have the connectors for this.
Otherwise have a look at the headunit wiring information dodo, and see what wires are used for the telephone / Bluetooth, see what plug the wires are connected to, and see if you can add those wires to the demon8 plug.
