GPS Navigation
GPS Overview
The GPS portion of your unit provides a method for navigation using
a system of overhead satellites to determine your location on the earth,
combined with a mapping database. Other built-in features allow you
to record waypoints (landmarks and destination points), find destination
points, (cities, points of interest, waypoints, etc.), chart your progress, and
monitor details such as speed, direction, and elapsed time.
Each time you turn on the unit, it must determine its location. The first
time you use your unit, this may take from five to fifteen minutes. After
first use, the unit should determine your location in less than one minute.
While the unit is collecting satellite information, a “searching for satellites”
window will appear in the lower left corner of the display.
When your location has been determined, the Map Navigator Page will
state “Ready To Navigate” and display Cardinal letters (North, South, East,
West) and your current location will be shown on the map above it.
If there are not enough satellites in view to determine its location, the
unit will display a “Poor Satellite Reception” message with four options. A
brief explanation for each option will appear when it is highlighted.
Use the ARROW keys to highlight the logical option and then press
the ENTER key to activate it.
If the time displayed in the time field on the Map Page is not correct,
you will need to set the time for your current location. Whenever the
unit is operating with GPS On, a Battery Life warning will appear. Press
ENTER to acknowledge.
