Question about Garmin GPSMAP 235 Sounder GPS Receiver
When I turn the unit on the screen flashes and immediately turn black.
Some 235s had a problem with the contrast setting. When the contrast is set to full the screen turns black.
When you turn on the GPS and the screen goes black, try tapping the left arrow on the track pad a few times. You should see the screen start to lighten. If that doesn't work, tap the power key and try tapping the left arrow a few times.
