RE: Reset Factory Radio
If you have a late model '04, the computer bus may be integrated with the audio system. If that was bypassed to install the aftermarket radio, you may have to go to the dealer to get it resolved. Are the factory speakers still in the truck? Or, aftermarket? Could be if they are aftermarket, the factory radio does not have enough oomph to drive the speakers.
