Always amazes me to see folks with real bright GPS screens mounted in line of vision at night - that blue light totally kills your night vision. When I am out on the open road at night I set the cruise and turn the dash lights off, I want to be able to see whats out there. Never have dash lights above anything but minimum brightness. There is a reason most airplane instruments are red instruments
are you sure those are gps, the last 4 gps I've had (I'm a service tech and use them every day so they wear out), have an automatic night mode, dull dark screen.
