AUDIO
DESCRIPTION
Several combinations of radio receivers and
speaker systems are offered. The audio system uses
an ignition switched source of battery current so that
the system will only operate when the ignition switch
is in the RUN or ACCESSORY positions.
A optional navigation radio (RB4) is available on
this vehicle. With this system, the operator has the
option of choosing a street address, point of interest,
trip itinerary and other features outlined in the oper-
ator's manual.
The audio system includes the following compo-
nents:
²Antenna
²Power amplifier (with premium speaker system
only)
²Radio noise suppression components
²Radio receiver
²Remote radio switches (if equipped)
²SpeakersCertain functions and features of the audio system
rely upon resources shared with other electronic
modules in the vehicle over the Programmable Com-
munication Interface (PCI) bus network. The data
bus network allows the sharing of sensor informa-
tion. For diagnosis of these electronic modules or of
the data bus network, the use of a DRB IIItscan tool
and the proper Diagnostic Procedures manual are
recommended.
OPERATION
The audio system components are designed to pro-
vide audio entertainment and information through
the reception, tuning and amplification of locally
broadcast radio signals in both the Amplitude Modu-
lating (AM) and Frequency Modulating (FM) com-
mercial frequency ranges.
The audio system components operate on battery
current received through a fuse in the Integrated
Power Module (IPM) on a fused ignition switch out-
put (run-acc) circuit so that the system will only
operate when the ignition switch is in the Run or
Accessory positions.
DRAUDIO/VIDEO 8A - 1
Page 387 of 2627
The optional navigation radio system receives GPS
signals from up to eight satellites to display the posi-
tion and direction of the vehicle. Map information is
supplied through a DVD-ROM. An electronic gyro-
sensor and the vehicle's speed sensor enable the sys-
tem to display the present vehicle position even in
locations where GPS signals may be blocked.
When a destination is selected, the navigation sys-
tem uses information from the map to quickly calcu-
late a route. As the vehicle is driven along the chosen
route, the operator is guided with pictorial displays
and voice prompts. For complete operating instruc-
tions, refer to the manual included with the vehicle.
On vehicles that are equipped with the optional
remote radio switches, the Instrument Cluster
receives hard wired resistor multiplexed inputs from
the remote radio switches. The programming in the
Instrument Cluster allows it to process those inputs
and send the proper messages to the radio receiver
over the Programmable Communication Interface
(PCI) bus network to control the radio volume up or
down, station seek up or down, preset station
advance, and mode advance functions.DIAGNOSIS AND TESTING - AUDIO
Any diagnosis of the Audio system should
begin with the use of the DRB IIItdiagnostic
tool. For information on the use of the
DRB IIIt, refer to the appropriate Diagnostic
Service Manual.
Refer to the appropriate wiring information.

DESCRIPTION
TELECOMMUNICATIONS
The hands-free cellular system on this vehicle uses
BluetoothŸ technology to provide wireless communi-
cation between the operator's compatible cellular
telephone and the vehicle's on-board receiver.
The system uses voice recognition technology to
control operation. The incoming voice is broadcast
through the vehicle's radio speakers, automatically
overriding any other audio signals on the front
speakers when the hands-free system is in use. A
microphone in the rearview mirror picks up vehicle
occupant's voices. If a call is in progress when the
ignition is switched off, the hands-free system will
continue to operate for up to 45 seconds as part of
the Accessory Relay Delay function. Thereafter, the
call can continue on the hand-held telephone.
The system will communicate with a telephone
that is anywhere within the vehicle. However, cover-
ing the hand held phone or the hands-free phone
module with a metal object may block the signal. The
system will recognize up to seven telephones, each of
which is given a spoken identification by the user
during the setup process. The system includes Span-
ish and French voice recognition in addition to
English.
Two buttons on the rearview mirror, identified with
ISO icons, control the system: A9phone9button turns
the system on and off; a9voice recognition9(or voice
command) button prompts the hands-free system to
listen for a voice command.
OPERATION
TELECOMMUNICATION
Two buttons on the rearview mirror, identified with
ISO icons, control the system: A9phone9button turns
the system on and off; a9voice recognition9(or voice
command) button prompts the hands-free system to
listen for a voice command. The system includes the
following features:
²Phone book - Stores telephone numbers for later
recall by name or other verbal identification, called a
voice tag, and memory location.
²Four memory locations - Home, Work, Cellular
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.
²Voice tag dialing - Dials the number associated
with a voice tag and memory location.
²Digit dialing - Dials the telephone number by
recognizing the names of the digits as they are spo-
ken.
²Receiving calls - A voice prompt notifies the user
of an incoming call. A voice response accepts or
rejects the call without manual intervention.
²Privacy Mode - Switches the call to the hand-
held telephone and the hands-free system and back
again using the ªvoice recognitionº (or ªvoice com-
mandº) button and a voice command, if desired.
