in cars that i had, i could shut off screens compleatly nav\ravio\back up cam.....etc, but i could not dim it, in some cars it is possible to change background color, it will make it a bit less bright, but still they are bright even than.
My screen dims with the dash lights, but not nearly enough when out in the middle of no where, so I am glad it also has the disable feature.
