You must go to your GMC Dealer. They can get a special code out of your radio then call an 800 number and it'll give them the unlock code. they will then enter that code they receive from the 800 into your radio and it will be unlocked. you might have to prove ownership of vehicle for then to do this - the reason for this is to prevent theft of radios
