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 .
Navigation System Components
The navigation system contains the following components:
• |
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 on the
roof of the vehicle and is connected to the navigation radio by a
coaxial cable. The antenna is used to collect the signals of the
orbiting GPS satellites, and is powered through the same coaxial
cable used to send the signals to the NAV radio.
Some vehicles may employ a signal splitter in the GPS antenna
coaxial cable. The signal splitter allows another device that
requires the GPS signals to be connected to the antenna along with
the navigation radio. The signal splitter divides the navigation
antenna signal into two paths without any transmission loss.
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.
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 is active. This feature only works if
the map DVD is inserted and the AGREE button has been pressed. For
a complete list of available commands, refer to the Owners Manual
Navigation Supplement and/or Personalization in the Owners
manual.
