Not sure if this is the proper forum. OEM replacement radio from same year (?04). Navigate thru Tech2 (clone) menu and after selecting the ?Relearn VIN? option and receiving a couple of ?Onstar not present, etc.) messages and finally selecting the erase auto-theft... prompt, it pauses and then displays ?Loss of Communications With Vehicle...??
Repeated this process several times with same result.
Repeated this process on my ?05 Avalanche with same results?
I know it is communicating with the vehicle because I could read/reset DTCs, retrieve other information, etc.
Any clues or another approach?
Thanks...
