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. SeeSymbols on page 4-36for more information
on the GPS symbol.
However, at times, other interferences such as the
satellite condition, road con guration, 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.
