GPS switched S for N!

When I got up to the mouth of the bay, I turned around and followed
the bug back south. [...] my destination was 5,900 miles distant, and
the time to
get there was 84 hours.

When I got home, I scanned out and out on the map, to find that my
waypoint was now located in the Andes on the Argentinian side of the
Chile-Argentina border.

What happened?

What happened was precisely why I am so vocal about paper charts and
against reliance on this newfangled gizmo thang. (and horrified at the
thought of central computer control of airplane systems)

As a cub driver you are probably with me on this. I've had my home
airport move to the other side of the country several times. Dunno why.

I use a KLN 94, but when I input coordinates and waypoints, I always
crosscheck the distances and bearing with a chart to see if everything makes
sense. Computerized systems do what we tell them to do, which is not
necessarily what we want them to do .

I had been using the waypoint in question for nearly a year, and had
used it most recently a week earlier.. It wasn't "input" incorrectly.
It actually changed from 42N to 42S in a 7-day period.

I didn't want to complicate the post, but another user-defined
waypoint also moved. In this case, it appears to have adopted the
coordinates of my home. This was Mountain View airport in Wolfeboro,
which I punched in a month ago in preparation for going to an open
house there. (In that case I didn't enter the coordinates, but put the
cursor on the map where I knew the airport to be, and punched it in.)
I did notice, when I was flying north to Lake Winnipesaukee on
Saturday, that the MtnView locator seemed to be in the middle of Great
Bay. But since I wasn't heading there, I ignored it.

For years I used a Garmin III+ (not aviation) and all my waypoints
were user-defined. I never had a problem with it.
