My Buick Terraza has a touch tone display screen in front for radio, dvd, navigation etc. Someone else had been driving it and later that
day when I got back in the screen is gray and only say's "this screen may appear reverse". No matter what I do it will not go back to the touch tone screen.
Do you have a suggestion on what I can do to make this work again. My manual only talks about a record radio system not the touch screen.
