point does not appear where the point should be, the map
datum and position format of the device may not match the map
datum and position format originally used to mark the waypoint.
Position format is the way in which the GPS receiver's position
appears on the screen. Commonly displayed as latitude/
longitude in degrees and minutes, with options for degrees,
minutes and second, degrees only, or one of several grid
formats.
Map datum is a math model which depicts a part of the surface
of the earth. Latitude and longitude lines on a paper map are
referenced to a specific map datum.
1
Find out which map datum and position format was used
when the original waypoint was created.
If the original waypoint was taken from a map, there should
be a legend on the map that lists the map datum and position
format used to create that map. Most often this is found near
the map key.
2
On the chartplotter, select Settings > Preferences > Units.
3
Select the correct map datum and position format settings.
4
Create the waypoint again.
