Another Expert here:
The above procedure will NOT work.
Because the Radio is a Class 2 DATA Type Radio, you will need Dealer to connect Scan Tool & download Radio Info to Computer & they then get the UNLOCK Code from GM & Upload back into the Vehicle
There is No Customer Unlock Code
this did notwork radio still says locked when press 1 and 4 button nothing happens held them for 30 seconds
You will need to have the Dealer Unlock it
you will need to take it to the dealer
