The Magellan GPS receiver can display position fixes in twelve of the most
commonly used datums. (Default is WGS84.) Using an incorrect datum may
cause the receiver to display position coordinates that differ from those on
the map. Whenever possible, set the receiver to use the datum that was used
to create the map or chart you are using; this information can be found in the
legend.
lf your map's datum is not defined in the receiver, you may be able to identify
a defined datum that is very close to it. Locate a nearby landmark on your
map and obtain a position fix there. Compare the coordinates to the ones
on the map, then select another datum. Use the datum that produces
position coordinates that are closest to the ones on the map.
lf you are not sure which datum was used to create your map, try the
procedure above, or use the datum the describes the area you are in. For
example, use NAD27 if you are in North America. When in doubt, use
WGS84.
