ways 1/4 the zoom range).

Map Datum Selection

Maps and charts are based on a survey of the area that's covered by the
map or chart. These surveys are called "Datums." Maps that are cre-
ated 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 da-
tum, which covers the entire world. Other datums may also cover the
entire world or just a small portion of it. By default, your position
shows using the WGS-84 datum. However, it can show your position
using one of 191 different datums. Different datums can be selected; to
change the datum:
1. Press |
