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 audio 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, located in the center of the instrument panel, provides the following:
| • | A display screen. All navigation and audio 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. |
| • | Provides verbal guidance to the operator. |
| • | The CD ROM 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 GPS antenna is located at the top center of the dash pad. The GPS Antenna is powered through the same coaxial cable used to send the signals to the navigation radio.
GPS Reception
The 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.
Point of Interest (POI)
Points of interests 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 |
Beam
The beam function allows the operator to send or receive data from a Palm Pilot. The IR port is located in the top right corner. Holding the Palm Pilot near this port and selecting transmit will send data to the navigation radio. This data can then be used to set a destination.
Map CD
The map CD is loaded in the CD slot above the display screen. When travelling from or to a different region, the map CD for that region must be loaded. Disc ten has major interstates and cities only. For detailed information in each region, use appropriate CD.
