Navigation System Components
The navigation system contains the following components:
| • | Navigation radio |
| • | Global positioning system (GPS) antenna |
Navigation Radio
This component acts as the operator interface for the navigation system, provides the data input from the operator to the navigation system and provides navigation information to the operator via the display screen. The navigation radio is located in the center of the instrument panel. The navigation radio provides the following:
| • | A display screen. All navigation, audio and TV functions are displayed on this screen. |
| • | The navigation system map with routing information displayed on the navigation radio screen. |
| • | Audio system options and controls, displayed on the navigation radio screen |
| • | The DVD provides the map data for navigation and map route guidance |
| • | Connection to the global positioning system (GPS) antenna, which provides the vehicle position information |
Global Positioning System (GPS) Antenna
The global positioning system (GPS) locates the current position of the vehicle using signals sent by GPS satellites. The GPS antenna is attached to the instrument panel (I/P) carrier and can be accessed by removing the I/P retainer. The GPS antenna is powered through the same coaxial cable used to send the signals to the navigation radio. Interference to the system may occur if any of the following exist:
| • | Signals are obstructed by objects such as, tall buildings or trees. |
| • | Metallic objects located on the dashboard |
| • | Aftermarket glass tinting has been applied to the vehicles windshield. |
GPS Reception
The global positioning system (GPS) shows the current position of the vehicle. Tall buildings, large trucks, or a tunnel can obstruct GPS signals. Metallic objects on the dash can also cause interference. A GPS icon is located in the top left corner of the map display. If the GPS is valid, the icon will be green if not the icon will be gray. The GPS info screen will also show the condition of the GPS. If GPS reception in not received, it will show out of range. If the reception is received, the coordinates of your location will be shown.
Route Guidance
The map will display the route to the selected destination. Voice prompts alert the operator of upcoming events (turns) and arrivals at the destination. The navigation system will automatically recalculate if the route is not followed. The navigation radio uses data received from the global positioning system (GPS) satellites as well as the vehicle speed signal to accurately display the current position of the vehicle.
Points of Interest
Points of interests (POI) are locations that are frequently visited. Points of interest can be displayed on the map or set as a destination. The following is a few of the available POI:
| • | Gas station |
| • | Restaurant |
| • | Museum |
| • | College |
| • | Police |
Map DVD
The map DVD is loaded in the DVD slot above the display screen. Music CDs can also be played from this slot, however, route guidance and navigation will not be available when playing a music CD. The map DVD must be in for navigation and route guidance.
