The end of last summer, my GPS chartplotter would continually shut off as I cruised thru choppy water. I could easily restart it , stayed on if I was at rest or idling in calm water. it got worse as the season closed.

My guess is that I have a loose or corroded connection (salt water) somewhere, maybe even a less than snug battery connection. I plan to check all the connections in the spring.

Does anyone think that there might be a loose connection or board in the unit itself? I would send it to the factory as a last resort since it is out of warranty.

Thoughts?

I was having the same problem on my Garmin GPSMAP 498C. I disconnected the connector to the unit and sprayed it with Corrosion X. I Let it sit for a little while hooked the connector back up and it has worked fine ever since. Mine would do the same as yours.... come on....fade away or I' d get the message "Updating Software" and then it would shut off.

Thanks Gary, I will add that to my list of remedies. : )

The problem can be the cheasy little inline fuse holders.
Ive taken mine out wired direct to my switchpanel which is already fuse and now no problems.

i had the same problem with my garmin unit at the end of the season last year. i installed a new power cable (i could see one of the female ends that was slightly damaged) sprayed everything with corrosion X and the unit has worked flawlessly this year.

Had the same problem....was just a loose connection at the battery terminal.
