[minino]

Hi guys I just joined when i woke up this morning my nav screen is blank -like a tv screen- it was ok when i parked 2 days ago and 24 hours rain. So Surprise. Its upsetting because of the ac Thats important I can drive without the maps. Design flaw because I dont know if I have an ac prblm ; fan prblm heater prbl?? Just because the screen shows NOTHING / anybody has had same nasty surprise did u get it resolved - appreciate suggestions including classaction suit because ac is safety in florida.thanks Minino
