Audio/Video ElectronicsWired up? If you have some sort of A/V modification let's hear about it here. Discussion of stock electrical problems should be done in the 'Lighting & Electrical' section.
I'm pretty sure that all GM radios from 2003 and up are paired with the BCM and are VIN locked requiring their programming tool to write the VIN to the radio, and I highly doubt that the databus system from the newer trucks would be compatible with our older trucks. Especially trucks older than 2003 when GM changed over to the newer system in the S-series trucks. I'm not saying it's impossible, but I have my doubts about it.
