Navigating to a Destination
Using the Nav Key
The NAV key provides three ways to navigate to a destination:
Go To Point, Follow Route, and Follow Track (TracBack). When
you are actively navigating, the Map Page displays a straight line
from your current location to the destination. The Go To option is
the easiest method for selecting a destination. A Go To allows you
to select a destination point and quickly set a direct course from
your present location. If you have a point highlighted on a list or
the map, Go To <point name> appears in addition to Go To Point.
The Go To function is accessed from any list of points or
graphically from the Map Page.
