Navigation System Components

The navigation system contains the following components:

    • Navigation radio
    • Global positioning system (GPS) antenna

The export navigation system contains the following additional components:

    • Vehicle information communication system (VICS) module
    • VICS optical beacon antenna
    • Four TV antennae integrated into the rear window glass
    • VICS FM antenna integrated into the rear glass
    • TV antenna module to control antenna selection
    • Antenna amplifier
    • Auxiliary RCA video jacks

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 keys on the right side of the display to allow selection from menus and to operate the navigation system, the audio system and the (export) TV system
    • The navigation system map with routing information displayed on the navigation radio screen
    • Plan a route and provide turn-by-turn route and map guidance with voice prompts
    • Select a destination from various areas and choices, such as:
       - Street address
       - Intersections
       - Previous destinations
       - Points of interest

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.

TV and VICS Antenna

These several antennas are conductive traces placed on the inside of the rear window glass.

TV Antenna Module

The TV antenna module is located under the rear window shelf. The TV antenna module is used by the navigation radio to automatically select the antenna combination that provides the strongest TV signal to the navigation radio. The TV antenna module also provides the vehicle information communication system (VICS) FM signal to the VICS module.

TV Antenna Amplifier

The TV antenna amplifier is mounted behind the trim on 1 side of the rear window. The TV antenna amplifier is powered by the TV antenna module through the same coaxial cable used to carry their signals to the TV antenna module. They are attached to the 4 TV antenna trace patterns in the rear window glass.

Auxiliary RCA Video Jacks

The auxiliary RCA video jacks, used to attach a remote video device, are located at the rear of the center console. These connections may be used to provide audio and video input from a video player or camera to the navigation radio.

VICS Module

The vehicle information communication system (VICS) module, an export only dealer-installed option, uses signals from the optical/microwave beacon antenna and the rear glass VICS antenna via the TV antenna module to convey routing information to the navigation radio. The navigation radio either revises planned routing or relays the VICS information to the operator through the screen of the navigation radio and the voice guidance system.

VICS Optical Beacon Antenna

The vehicle information communication system (VICS) optical beacon antenna is a dealer-installed option. The antenna, which is mounted on the right side of the instrument panel, picks up signals through the front window glass. A coaxial cable carries the power to and signals from this antenna to the navigation radio.

Browser

Important: This function is for view files on disk only. The navigation radio cannot get external files from the World-Wide Web or other sources other than an inserted disk.

The navigation radio will allow HTML files to be displayed. The files will only be able to be accessed and viewed. No user input is capable.

Planning a Route

To plan a route a destination must be set. There are various types of destinations available, as listed above. Pressing "Calc" once the destination has been entered will plan the route. To start the route guidance start driving the vehicle. The route guidance will begin automatically after a short distance.

Beam

The beam function allows data to be sent by a PALM hand held computing device directly into the navigation system. The IR port for the beam function is located in the upper right corner of the navigation radio.

Voice Recognition

The Navigation Systems 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. The memory seats can also be able to be set and selected using the voice recognition feature. For a complete list of available commands, refer to the Owners Manual Navigation Supplement and/or Personalization in the Owners manual.
