‘hddd°mm.mmm’ displays the latitude and longitude in
degrees and minutes and is most commonly used.The
following additional formats are available:

Using the LORAN TD Format
When creating new waypoints using LORAN TD
coordinates, you must set the correct LORAN chain num-
ber and secondary stations in the Setup TD fi eld before
storing the waypoint. After the waypoint is stored in unit
memory, it will always reference the LORAN chain num-
ber and secondary stations currently selected in the Setup
TD fi eld. If you enter a different LORAN chain number,
change the secondary stations or offsets in the Setup TD
fi eld, the active waypoint information will refl ect those
changes. Since the GPSMAP unit does not rely on the
LORAN signal for navigation, it can reference a different
GRI chain and/or secondary stations and still navigate to
the location stored in memory.

The ‘User’ datum is based on
a WGS-84-Local datum and
is an advanced feature for
unlisted or custom datums. To
