I have a 2006 DC Limited with the E7006. In the first 5 months of owning this great truck everything worked great. My first and only problem has been when I have the "audio" screen on, when selecting a preset radio station or when I have the screen on that shows what track my CD is playing, after about 30 seconds the screen goes blank(basically shuts off). When I first bought this truck the screen would stay on until I shut off the truck. I would like the screen to stay on until I say so!! Does anyone have any tricks they can share to help remedy my problem?
