My garmin 172C gps fades quickly when exposed to direct sunlight. I sent it back to garmin, they replaced it and it does the same. I keep it covered most of the time unless I need it. Any better units ?? Thanks, Dave

I think its not your GPS unit, may be powersorce on your plug ?!


I have the same in my boat works great, even bought it used .
The only problem i had was the plug in the back, new cable now fine.

same here, it used to cut out and it was the cable. try that first.. mark

Most of the time it's that little crimp on fuse holder they use.

This unit may be equipped with a Thrill-Seeker chip. Your GPS might just be getting bored with the slow-azz speeds your running. Try flooring the boat and see if it wakes-up!

Is 95+ quick enough? Anyhow...The electronic part seems fine, it tracks and the speed readouts are good. It just gets fainter and fainter in the direct sun. I cover it and its bright again..

Somebody has to have some thoughts here.......
