Updating waypoints?? Mine go back 20 years. I believe they took the “man made error” of the system during the Clinton Administration. I remember the American dude at the North Pole on live TV saying in the presence of one of the Russians “Should I tell him we’re really 100 feet away from the pole?”
I think my hand-held Garmin is seldom accurate to more than 15 ft., so I guess I can save myself the trouble.
