My 06 Envoy Denali factory Non-Lux NAV radio is broken. I even tried to have it repaired – it’s not repairable. I can obviously buy a used one. I have a Tech-II scan tool. Does this mean I can program the new radio with the VIN of my car so Theftlock will allow the radio to play? Or do I need some other device to reprogram the used radio, i.e., I still have to take the car to the dealer. Any help would be appreciated.
