AUDIO/VIDEO
DESCRIPTION
An audio system is standard factory-installed
equipment on this model. A rear seat video system is
an available option. Several combinations of radio
receivers are offered on this model. The audio/video
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/
ACCESSORY DELAY positions.
The audio system includes the following compo-
nents:
²Antenna
²CD changer (if equipped)
²DVD player (if equipped)²Radio noise suppression components
²Radio receiver
²Speakers
²Video screen (if equipped)
Certain functions and features of the audio/video
system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communication Interface (PCI) bus network. The
data bus network allows the sharing of sensor infor-
mation. 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.
Refer to the appropriate wiring information in this
service manual for complete standard and premium
audio system circuit diagrams. The wiring informa-
tion includes proper wire and connector repair proce-

ANTENNA BODY AND CABLE
DESCRIPTION
All models use a fixed-length stainless steel rod-
type antenna mast, installed at the right front fender
of the vehicle. The antenna mast is connected to the
center wire of the coaxial antenna cable, and is not
grounded to any part of the vehicle.
OPERATION
To minimize static, the antenna base must have a
good ground. The coaxial antenna cable shield (the
outer wire mesh of the cable) is grounded to the
antenna base and the radio chassis.
The antenna coaxial cable has an additional dis-
connect, located near the right end of the instrument
panel. This additional disconnect allows the instru-
ment panel assembly to be removed and installed
without removing the radio.

The ohmmeter test lead connections for each test
are shown in (Fig. 1).
TEST 1
Test 1 determines of the antenna mast is insulated
from the base. Proceed as follows:
(1) Unplug the antenna coaxial cable from the
radio chassis and isolate. Remove the antenna mast.
(2) Connect an ohmmeter test lead to the inside
center of the antenna base. Connect the other test
lead to a metallic portion on the outside of the
antenna base. Check for continuity.
(3) There should be no continuity. If continuity is
found, replace the faulty or damaged antenna base
and cable assembly.

CD CHANGER
DESCRIPTION
The 6 Disc In-Dash CD Changer (if equipped) is
located in the instrument panel below the radio. The
remote changer does not use a cartridge or magazine
for the CD's. Up to 6 CD's can be directly loaded into
this unit.
OPERATION
Due to its compact design, the CD changer can
carry out only one operation at a time. For example,
you can not load a new disc while playing another at
the same time. Each operation happens sequentially.
The radio unit provides control over all features of
the CD changer with the exception of the CD load
and eject functions, which are controlled by buttons
located on the front of the CD changer. All features
you would expect, such as Disc Up/Down, Track
Up/Down, Random and Scan are controlled by the
radio, which also displays all relevant CD changer
information on the radio display.
The CD changer contains a Eject button, six disc
buttons, an indicator LED for each of the six disc
positions as well as an illuminated disc opening. The
individual LED indicates whether a CD is currently
loaded in that particular chamber of the CD changer.
Pressing the individual button for a particular cham-
ber, then the Eject button will eject a disc currently
present in that chamber. If the chamber is currently
empty, actuating the individual button will position
