Global Positioning System (GPS)The Navigation System determines the position of yourvehicle by using satellite signals, various vehiclesignals and map data.At times, other interferences such as the satellitecondition, road configuration, the condition of the vehicleand/or other circumstances can interfere with theNavigation’s ability to determine the accurate position ofthe vehicle.The GPS shows the accurate current position of yourvehicle using signals sent by the GPS Satellites ofthe United States Department of Defense. When yourvehicle is not receiving signals from the satellites,a symbol will appear on the map screen. Refer toSymbols on page 2-6.This system may not be available/or interference mayoccur if the following happens:• Signal obstructions caused by tall buildings, largetrucks, tunnels,• objects located on top of the instrument panel,• satellites will not send signals if they are beingrepaired or improved,• after-market glass tinting has been applied to thevehicle’s windows.Notice: Do not apply after-market glass tinting tothe vehicle’s windows. Glass tinting will interferewith the system’s ability to receive GPS signals andcause the system to malfunction. You might haveto replace the window to correct the problem.This would not be covered by your warranty.For more information if you are experiencing a problem,see If the System Needs Service on page 2-70 andProblems with Route Guidance on page 2-69.2-67
