I know it can work but my question is do I have to install the 08 head unit first? Then take the car to the dealer? I don't think this would work as the head unit has a security lock out, or does it not matter?
Secondly anyone a GM tech that can do it cheaper than $100+ that the dealership wants to flash it? They said it takes an hour to flash the headunit....
