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 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 positions

are shown on all screens. This includes waypoints.
