Gee, I'm surprised Garmin doesn't have a better dimmer circuit. My AvMap
has a dimmer circuit that tones it all the way down to nuthin'.

In fact, we actually thought the unit was broken one day when it wouldn't
"power up." It turned out we had dimmed it so much the night before that
we couldn't see it in the daylight!
