I'm having a problem with my G1W where the screen will not turn on. It just started yesterday; the screen was on when I got out of the truck, but it was off when I got back in later. They G1W was plugged in and on the whole time. I unplugged for a while and the screen came back on again when I turned it back on, but today it won't come on at all. Also, I noticed the the red LED is blinking 3 times: 1, pause, 2,3. Any help would be appreciated.
