command) button prompts the hands-free system to
listen for a voice command.
OPERATION
NAVIGATION
The Navigation System uses a Global Positioning
System (GPS) antenna mounted under the instru-
ment panel to collect satellite data to compute the
position of the vehicle. A navigation unit uses the
satellite data to translate the vehicle location to lat-
itude and longitude coordinates. It combines the lat-
itude and longitude with proprietary map data from
a DVD unit to perform all system calculations and
display formatting. A single DVD disc contains map
information for the entire United States. The DVD
unit is mounted in the covered underfloor storage
compartment at the rear of the vehicle. The map
database information works with the application soft-
ware to perform the following operations:
• Map Guidance
• Vehicle Positioning
• Address Retrieval
The system provides the following additional capa-
bilities:
• Increase or decrease map scale using ENTER
and direction arrows
• Scroll through map to a desired destination and
press ENTER to begin routing
• Cancel route guidance
• Change language via the EVIC system using the
MENU and STEP buttons
• Change display measurement units using the
US/M button (Changes units for all displays in the
vehicle)
TELECOMMUNICATION
Two buttons on the rearview mirror, identified with
ISO icons, control the system: A phone button turns
the system on and off; a voice recognition (or voice
command) button prompts the hands-free system to
listen for a voice command. The system includes the
following features:
• Phonebook - Stores telephone numbers for later
recall by name or other verbal identification, called a
voice tag, and memory location.
• Four memory locations - Home, Work, Mobile
and Pager. A maximum of 32 unique names or voice
tags may be stored at the same time, with a different
number in each of the four memory locations.
• Voice tag dialing - Dials the number associated
with a voice tag and memory location.
• Digit dialing - Dials the telephone number by
recognizing the names of the digits as they are spo-
ken.
• Receiving calls - A voice prompt notifies the user
of an incoming call. Pressing the "phone" button
answers the call.
• Privacy Mode - Switches the call to the hand-
held telephone and the hands-free system and back
again using the "voice recognition" (or "voice com-
mand") button and a voice command, if desired.
ANTENNA - NAVIGATION
DESCRIPTION
The navigation antenna is mounted on top of the
instrument panel below a trim panel on the left side.
The antenna is secured with two fasteners. The
antenna cable is routed along the instrument panel
wire harness from the left side to the right side of
the vehicle and has a connector located near the
front passenger door.
OPERATION
The navigation antenna receives signals from orbit-
ing satellites and sends these signals to the naviga-
tion unit located in the rear of the vehicle. The
navigation antenna must have open space in which
to operate. items placed over the antenna, parking
inside etc. can have an effect on the antenna's ability
to receive signals.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the instrument panel top cover (Refer
to 23 - BODY/INSTRUMENT PANEL/INSTRUMENT
