I am selling my navigation system because Im not sure how to fix it. The entire unit works properly except for what seems to be a backlight or bulb for the lcd screen. you can see things, just not well. Could be something minor Im not sure...seems like alot of people around here are electronic savy ...

Hi I am new here, but a long time reader just without registering. My navigation screen will not come on anymore after I left my windows down witht he sprinklers on. Not much water, but must have done something. Anyways the entire readio works, all buttons, all sound- just no screen..any help?
