front of the unit allow the use of MP3 players, video
game systems, camcorders etc.
OPERATION
Due to its compact design, the CD/DVD changer
can carry out only one operation at a time. For exam-
ple, 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/DVD changer with the exception of the
CD/DVD load and eject functions, which are con-
trolled by buttons located on the front of the CD/DVD
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 rele-
vant CD/DVD changer information on the radio dis-
play.
The CD/DVD 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/DVD is
currently loaded in that particular chamber of the
CD/DVD changer. Pressing the individual button for
a particular chamber, 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 that chamber to receive and load
a new disc in that chamber, once the load light stops
flashing.

QUARTER GLASS INTEGRAL
ANTENNA
DESCRIPTION
The quarter glass integral antenna element is
bonded to the right rear quarter glass and is replaced
with the glass assembly only.
OPERATION
The integral antenna receives radio frequencies
and sends them to the antenna module for amplifica-
tion.
DIAGNOSIS AND TESTING - QUARTER GLASS
INTEGRAL ANTENNA
The antenna grid pattern is divided into two sepa-
rate patterns. Each terminal connects to a separate
grid pattern, one for AM and the other for FM.
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds. To detect breaks in the
integral antenna elements, the following procedure is
required:
(1) Disconnect the antenna module connector from
the antenna terminals on the glass.
(2) Using an ohmmeter, place a lead on one of the
terminals and check each end of the grid pattern con-
nected to this terminal for continuity. If continuity is
not present, move one lead through the grid in pro-
gression starting at the terminal with the other lead
on the terminal until continuity is lost. Repeat pro-
cedure for the other terminal. A break in the antenna
grid can be repaired using a Mopar Rear Window
Defogger Repair Kit or equivalent.
RADIO
DESCRIPTION
Available radio receivers include:
• AM/FM/MP3/CD with CD/DVD changer control
(RAH sales code)
• AM/FM/MP3/cassette/CD/equalizer

OPERATION
The radio receiver operates on ignition switched
battery current that is available only when the igni-
tion switch is in the On or Accessory/Accessory Delay
positions.

RADIO NOISE SUPPRESSION
COMPONENTS
DESCRIPTION
Radio noise suppression devices are factory-in-
stalled standard equipment on this vehicle. Radio
Frequency Interference (RFI) and ElectroMagnetic
Interference (EMI) can be produced by any on-board
or external source of electromagnetic energy. These
electromagnetic energy sources can radiate electro-
magnetic signals through the air, or conduct them
through the vehicle electrical system.
When the audio system converts RFI or EMI to an
audible acoustic wave form, it is referred to as radio
noise. This undesirable radio noise is generally man-
ifested in the form of “buzzing,” “hissing,” “popping,”
“clicking,” “crackling,” and/or “whirring” sounds. In
most cases, RFI and EMI radio noise can be sup-
pressed using a combination of vehicle and compo-
nent grounding, filtering and shielding techniques.
This vehicle is equipped with factory-installed radio
noise suppression devices that were designed to min-
imize exposure to typical sources of RFI and EMI;
thereby, minimizing radio noise complaints.
Factory-installed radio noise suppression is accom-
plished primarily through circuitry or devices that
are integral to the factory-installed radios, audio
power amplifiers and other on-board electrical com-
ponents such as generators, wiper motors, blower
motors, and fuel pumps that have been found to be
potential sources of RFI or EMI. External radio noise
suppression devices that are used on this vehicle to
control RFI or EMI, and can be serviced, include the
following:
• Cylinder head-to-cover ground strap - This
length of braided ground strap (2) has an eyelet ter-
minal connector crimped to each end. One end is
secured to the engine cylinder head(s). The other is
secured to the valve cover.
• Resistor-type spark plugs - This type of spark
plug has an internal resistor connected in series
between the spark plug terminal and the center elec-
trode to help reduce the production of electromag-
netic radiation that can result in radio noise.
OPERATION
There are two common strategies that can be used
to suppress Radio Frequency Interference (RFI) and
ElectroMagnetic Interference (EMI) radio noise. The
first suppression strategy involves preventing the
production of RFI and EMI electromagnetic signals
at their sources. The second suppression strategy
involves preventing the reception of RFI and EMI
electromagnetic signals by the audio system compo-
nents.
The use of braided ground straps in key locations
is part of the RFI and EMI prevention strategy.
These ground straps ensure adequate ground paths,
particularly for high current components such as
many of those found in the starting, charging, igni-
tion, engine control and transmission control sys-
tems. An insufficient ground path for any of these
high current components may result in radio noise
caused by induced voltages created as the high cur-
rent seeks alternative ground paths through compo-
nents or circuits intended for use by, or in close
proximity to the audio system components or circuits.
Preventing the reception of RFI and EMI is accom-
plished by ensuring that the audio system compo-
nents are correctly installed in the vehicle. Loose,
corroded or improperly soldered wire harness connec-
tions, improperly routed wiring and inadequate audio
system component grounding can all contribute to

the reception of RFI and EMI. A properly grounded
antenna body and radio chassis, as well as a shielded
antenna coaxial cable with clean and tight connec-
tions will each help reduce the potential for reception
of RFI and EMI.

(1) Disconnect and isolate the battery negative
cable.
(2) Remove the mounting fasteners (Fig. 11).
(3) Remove the ground strap.
INSTALLATION
(1) Position ground strap and install mounting fas-
teners.
