Datum In order for your GPS
and chart to correlate
accurately with your
paper charts, they must
be using the same
datum. The default
datum for your display
is WGS1984. If this is
not suitable, you can
change the setting.
When you change the
datum setting, the chart
grid will subsequently
move according to
the new datum, and
the latitude/longitude
of the cartographic
features will also change
accordingly. The system
attempts to set up any
GPS to the new mode,
and indicates whether
this was successful or
not. • WGS1984 (default)
