Anyone wanting to do the bluetooth mod to their non '09.5 G8 can walk right into their local GM dealer and just order one brand new,just have the partsman state there will be no core vcim and also order the b/t antenna.Then any GM service dept. can program it to your vehicle.After searching on and off for a used vcim and the rediculous prices some want,I just stopped and thought, i work for a dealer all my life and just asked the parts guy to see if he can just order me the parts, minus core and he was able to, no questions asked by the supplier.,Anyone need any assistance with yours PM me
