Please help..997 night viewing
Getting ready to fish a night bass tournament this weekend and I won't be able to check out my manual before the tournament. I will need to be able to see the GPS charts while running, but I know it will be blinding if I leave the unit's settings as they are during the day. What do I need to do to keep the unit from blinding me w/ it's bright lighting during the night where I still the the charts, but also see past the unit while running.
The GPS in my truck automatically changes to a black background at night to keep from blinding you and I was wondering how I could make my Hummingbird 997 do the same thing.....thanks in advance for the help!
