Changing the Location Format
When you change the Location Format, you change the coordinate
system in which a given location reading appears. The default
format is latitude and longitude in degrees, minutes, and thousandths
of a minute (hddd°mm.mmm). Only change the location format if
you are using a map or chart that specifies a different location format
or want to use a format you are familiar with.
Selecting a Different Map Datum
Datums are used to describe geographic positions for surveying,
mapping, and navigation and are not actual maps built in the unit.
Only change the datum if you are using a map or chart that specifies
a different datum.
