Maps that are created using different datums will show the same
latitude/longitude in slightly different locations.
All datums are named. The GPS system is based on the WGS-84
datum, which covers the entire world. Other datums may also cover the
entire world, or just a small portion of it. By default, your unit uses the
WGS-84 datum. It, however, can show your position using one of 191
different datums. To change the datum:
1. Press
MENU|MENU|↓ to GPS SETUP|ENT|↓ to DATUM SELECTION|ENT.
2. Scroll ↓ or ↑ to select the desired datum, then press ENT.
3.
