About half way through our snow run yesterday, the screen on my 730N RER head unit faded to a white-yellow :idontknow: The screen still reacts to touch input (although I can't see what I'm touching...) and the hard buttons still function as well. It also still reacts to day/night input from the headlights as the blank white screen dims slightly when the headlights are turned on. Cycled the key at least a doze times throughout the rest of the day yesterday, and sitting overnight with the battery disconnected has not done any magic either. Any hopes for a simple repair or am I looking at needing a replacement head unit?
