Not true. He can blow out what is in there. I bought a TNR nav for my 03 Avalanche. There is no real way to divorce it. The idea is that only a dealer with a computer can make it work. Took the tech about 2 min and I was out the door. Gave him 20 bucks for doing it on the side and being a swell dude.
