In Canada, it gets cold. Real cold. It was -20 to -30 degrees C the last couple of weeks, and similar to the heat cycling of a windshield, the heat cycling of the LCD screen may have cracked it. There isn't any scratching on the outer surface. At first I thought frost had formed on the inside, but that spot seems have gotten larger and larger and doesn't go away after the car has warmed up. I'm taking it in as warranty work.
