Colors on the Screen
When a route has been planned, it will be
highlighted on the screen in blue. If you have set
a waypoint(s) for your route, the colors on the
screen will change. The highlighted route to the
next waypoint or destination will be blue. All
highlighted routes to further waypoints or
destinations will be maroon.
Different colors are also used to distinguish
between interstate freeways, state highways,
county roads, major streets and secondary streets.
Highways will be shown as a thicker line than a
general street will.

Global Positioning System (GPS)
The navigation system determines the position of
your vehicle by using satellite signals, various
vehicle signals, and map data.
The Global Positioning System (GPS) locates the
current position of your vehicle using signals
sent by the United States Department of Defense
GPS satellites. While your vehicle is receiving
signals from these satellites, the GPS symbol will
not appear on the map screen.
However, at times, other interferences such as the
satellite condition, road configuration, the
condition of the vehicle, and/or other
circumstances can interfere with the system’s
ability to determine the accurate position of
the vehicle. This is when the GPS symbol will
appear on the map screen.
