Coordinates
Coordinates: The coordinates destination entry method
allows you to select a destination by entering latitude
and longitude coordinates.
1. Press the DEST hard key.
2. Select the From Map screen button.
3. Select the Coordinates screen button, then enter
the numeric portion of the latitude and longitude
coordinate.
4. Once both coordinates are entered, select the OK
screen button. The map screen, with the scrolled
location, will display.
5. Select the Go screen button.
If the coordinate is near a street or POI, the system
will calculate a route to that street or POI.
The system will provide straight-line direction to the
coordinate if there is no street or POI nearby.
See "Getting Started on Your Route" later in this
section.
