yo my screen last week just went blank for no reason. I can tell that it still works because it still makes a noise when i touch the screen and if there is a light hitting the screen i can lighty see some of the screen menus, but this is bullshit. The screen is just black and i never had problems with it before. i paid a lot of money for the AVIC N1 and it worked fine for over a year. anyone know how to fix this? or is this something that cant be fixed? thanks to those who respond
