I am having an issue with a 2002 HSE. The radio...only getting sound from the front channel and the sub. I changed out the amp real quick and it changed nothing. The Nav...just a blank white screen. I don't actually have the disc that goes with it but I thought it would display "something"....:banghead: :rofl: Wot's the deal? I haven't had a chance to even begin to sort it out. Anyone have any idea what is going on before I begin chasing the devil?
