bose navigation h2 radio
 

Does anyone know what causes the screen on the radio to go white.radio, satalite radio and navagation still works fine . just no screen .greyish white with a few lines through it. Any help would be greatly appreciated .

you need a new radio?

I would do a rest on it. Some of the radios have a reset function in the menus or a small little button within the control panel. If you have neither, disconnect the battery.
