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, GPS will not appear on the map screen.
However, at times, other interferences such as
the satellite condition, road conguration, 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 GPS will appear on
the map screen.The system may not be available or interferences may
occur if any of the following are true:Signals are obstructed by tall buildings, large trucks
or a tunnel.
Metallic objects are located on the dashboard.
Satellites are being repaired or improved.
Aftermarket glass tinting has been applied to the
vehicle’s windshield.
Do not apply aftermarket glass tinting to the vehicle’s
windshield or place metallic objects on the vehicle’s
dashboard. Glass tinting and metallic objects will
interfere with the system’s ability to receive GPS signals
and may cause the system to malfunction.
