I have a 2005 Honda pilot, the navigation screen is cracked and there is a film behind it that has wrinkled up and faded where I cannot see the screen, is there a way for me to remove the nav faceplate so I can clean out that wrinkled crap? the unit works and all i can set destination and all but only at night in dark. It is a Alpine unit and it is only for navigation. PLEASE HELP!!
