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.
