Audio System Description
The Navigation radio operates similar to a traditional radio. For information on the audio description and operation, see Radio/Audio System Description and Operation (Radio/Audio System Description and Operation)
Navigation System Components
The navigation system contains the following components:
* Navigation radio
* Global positioning system (GPS) antenna)
* Auxiliary RCA video jacks (If Equipped)
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.
* Soft key buttons on the display to allow selection from menus and to operate the navigation system and the audio system.
* The DVD provides map data for navigation and map route guidance.
* The navigation system map with routing information displayed on the navigation radio screen.
* Provides verbal guidance to the operator.
* Connection to the global positioning system (GPS) antenna, which provides the vehicle position information.
Global Positioning System (GPS) Antenna
The global positioning system (GPS) antenna is located in the upper center of the I/P. The GPS antenna is powered through the same coaxial cable used to send the signals to the NAV 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.
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. The map DVD must be in the NAV radio for route guidance.
Auxiliary RCA Video Jacks (If Equipped)
The auxiliary RCA video jacks are used to attach a remote video device. These connections may be used to provide audio and video input from a remote device such as a video game console or camera to the rear seat entertainment system.
Voice Recognition
The Navigation System's voice recognition allows for hands-free operation of navigation and audio system features. The voice recognition can be used when the ignition is in accessory or ON, or when retained accessory power (RAP) is active. This feature only works if the map DVD is inserted and the AGREE button has been pressed.
Points of Interest
Points of interests (POI) are locations that are frequently visited. Points of interest can be can be displayed on the map or set as a destination. The following are some of the available POI:
* Gas Station
* Restaurant
* College
* Police Station
