This unit can show a position in degrees (36.14952°); degrees, minutes
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan, Greek and Military grids.

UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.

British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are each the national coordinate system used
only in their respective countries. In order to use these grid systems,
you must be in the respective country. This unit will pick the matching
datum for you when you select the grid. See the entry on Map Datum
Selection for more information.

The military grid reference system (MGRS) uses two grid lettering
schemes, which are referred to as standard and standard + 10 MGRS
on this unit. Your position and datum in use determines which one to
use. If you use standard, and your position is off significantly, then try
the alternate.

NOTE: When the position format is changed, it affects the way all posi-
tions are shown on all screens. This includes waypoints.
