Humminbird Shutting off Issues

[searaydiver]

My bird was turning itself off and then back on by itself. I checked all the dumb stuff such as the connections, etc. but could not find an obvious problem so I called the bird people. What they told me was hard to fathom but turned out to be accurate. The bird has a habit of creating false waypoints, especially if you have waypoints in there for some time. You need to go thru and look for waypoints that have weird symbols such as#,@,&. You get the point. My unit made up waypoints that where nowhere near my area, like down in south Fla. I found 5 bogus points and deleted them and now the unit works like a new bird. The unit is a 797C2 that's about four years old.
I hope that this bit of info will help someone.
