1.2 Horn Bar Stereo Control Operation
There are two major components of the horn bar stereo
control system. These components are as follows:
Left-hand switch assembly (1)
Located to the left-hand side of the horn bar, the left-
hand switch assembly has three momentary contact
switches that are used to control the mode of operation
and switching between preset stations.
The MODE button allo ws selection between the Radio
Mode of operation and the C D Mode.
If Radio Mode is selected, the NEXT UP button selects
the next preset station in the frequ ency band, while the
NEXT DOWN button selects the previous preset radio
station.
If CD Mode is selected, the NEXT UP button selects the
next track on the CD, while the NEXT DOWN button
selects the previous track. For CD Changer models,
pushing the NEXT UP and NEXT DOWN buttons
simultaneously changes the di sc.
Right-hand switch assembly (2)
Located to the right-hand side of the horn bar, the right-
hand switch assembly has three momentary contact
switches that are used to control the MUTE functio n as
well as the VOLUME UP and VOLUME DOWN.
Each control switch has a unique resistance value. When
a button is pressed on the horn bar contro l, the AHU
decides the function required by measuring the
resistance of the contact pressed.
Wiring (3) from the right-hand sw itch is connected to the
left-hand switch. The left-hand switch is conne cted to the
audio system head unit by a wiring loom (4). Figure 12D – 3
shows the wiring details for the non-illuminated horn bar
stereo controls and Figure 12D – 4 show s the w iring details
for the illuminated horn bar stereo controls.
Figure 12D – 2
A Multi-function Display (MFD) in the instrument panel can provide the driver with an almost line-of-sight view of the MFD
for ease of operation of the audio system from the horn bar buttons.
Normal display on the MFD durin g vehicle operation displays the normal trip computer functions, for example the
odometer (in the centre of the MFD screen) and the g ear selector position (displayed at the bottom of the MFD screen at
all times).
When the radio or a CD source is selected, the rad io band and frequency or the CD symbol replaces the trip computer
display for two seconds. The display then reverts to the trip computer display with the radio band and frequency or CD
and track indicator changing to a secon dary small icon located in the warning icon location on the left-hand side of the
MFD.
IMPORTANT
If a warning is activated, the warning will override
the CD and track indicators.
The display of audio system information on the MFD can be turned On or Off from the MFD. The default setting is On.
Refer to Section 12C, 1.8 Customisation Mod e in the MY 2003 VY and V2 Series Service Information for further detai ls.
For Level 1 Acclaim Sedan and W agons and all Level 3 Models, the horn bar stereo controls are illuminated whenever
the park lamps or headlam ps are turne d on. The intensity of the illuminat ion cannot be varied.

1.3 On-glass Antenna System
Overview
For MY2004 V2 Series vehicles, an on-glass antenna on the rear window replaces the standard mast a ntenn a. The on-
glass antenna system consists of an antenna coil assembly L4, an antenna amplifier module A93 and connecting leads.
The antenna cabl e between the audio head unit and the antenna amplifier module is a t wo-piece coaxial cable with an in-
line connector located behind a panel in the left hand foot well.
The antenna coil assembly comprises two antennas, one for AM signals and another for FM signals, and these form an
integral part of the rear window glass. The FM antenn a coil is also used as the rear window demister element. The thin
conductors that form each antenna are laid on the inside of the glass, and two connectors are located on the side of the
rear window allowing connection of the antenna coils to the antenna amplifier module. The F M antenna coil / demister is
connected to body ground at X118_GP7, via circuit 185 0, which also includes an RF isolation coil.
The antenna amplifier module amplifies the small signals from the antenna coil assembly then transmits the amplified
signal to the audio system head unit antenna input via a coaxial cable, circuit 5172.
A single wire lead, circuit 314, from the audio system head unit provides the +12 V supply to the antenna amplifier
module for its operation.
The module is grounde d through its case to the vehicle body. To prevent interference, it is very important that the module
and coaxial cable are gro unded securely. Refer to Figure 12D – 10 and Figure 12D – 11 for the antenna interconnection
details.
Figure 12D – 5 illustrates the location of the antenna amplifier module and the routin g of the antenna cable,

The MY2004 V2 Series vehicles are fitted with th ree on-g lass ante nna s mounted on the rea r w indow . This an tenna sy stem
eliminates the need fo r the use of a mast type an tenna on the veh icle. The antenna co il asse mbly comp ri ses th ree an ten nas
plus provision for an external mob ile phone an tenna. Refer to Figure 12 D – 6 and Fi gure 12D – 7.
Figure 12D – 6
AM Antenna
A single AM antenna system is mounted on the rear glass a ssembly (L4, X1-A). Refer also to item 2 in Figure 12D – 7.
FM Antennas
There are two FM antenna s ystems mounted on the rear glass assembly:
• A combined FM Main antenna and demister element (L4, X2-A; X3-A). Refer to item 4 in Figure 12D – 7.
• A FM Diversity antenna (W4). Refer to item 3 in Figure 12D – 7.
The thin conductors that form each antenna are fixed o n th e inside of the glass, and the antenna / demister electrical
connectors are located on the side of the rear window. The FM Main antenna / demister is connected to body ground at
X118_GP7, via circuit 1850, which also inc ludes an RF isolation coil.
The N3 Antenna Amplifier module amplifies the FM Diversity antenna sign als to help red uce noisy radio reception that
may be generated within the vehicle. This module is mounted in the C-pillar as shown at item 9 in Figure 12D – 10.

Window tinting is not recommended on any
glass that has printed antenna coils attached.
Metallic-based tint material significantly
reduces radio reception in both the AM and
FM bands, whereas dye-based tint material
reduces reception in the FM band.
Installation of a mobile phone antenna pad to
the surface of the on-glass antenna may lead
to interference betw een the audio system and
the mobile phone antenna. Figure 12D – 7
indicates the recommended location for the
mobile phone antenna pad in order to
minimise interference.

A93 Antenna Module Overview
The vehicle’s FM Main antenn a and its comb ined demister element connect to the audio system and demister circuit via
the A93 Module assembly and its connecti ng leads.
The AM antenna receives AM band radio signals and feeds them to a radio frequenc y amplifier located within the A93
module. Refer to Figure 12D – 8. Similar ly, the FM band radio signals are received b y the F M Main Antenna (i.e. via the
demister element) and are fed to the F M Main Antenna radio frequency amplifier also located within the A93 module.
Both of these amplifiers feed their amplified radio signals into a Radio Frequency Mixer (or combiner) unit. The output
signals of this unit contain radio signals of b oth the AM and FM Main antennas that are then fed into the antenna input of
the vehicle’s A133 AHU.
Figure 12D – 8
Circuit 5172 is a coaxial cable that carries the combined AM and FM Main antenna signals to the A133 AHU antenna
input. It is a two-piece coaxial cable with an in-line connector located behind a panel in the left-hand side footwell.
Circuit 314 is a single wire lead that originates from the A133 AHU unit, which provides the +12 V supply to the antenna
amplifier module.
The module is grounde d through its case to the vehicle body. To prevent interference, it is very important that the module
and coaxial cable are gro unded securely. Refer to Figure 12D – 10 and Figure 12D – 11 for the antenna interconnection
details.
Entertainment System Page 12D–13
Page 12D–13
N3 Antenna Amplifier Module Overview
The vehicle’s FM Diversity antenna connects to the A133 AHU audio system via the N3 Amplifier assembly. This module
is shown as (item 9) in Figure 12D – 10. The routing of the FM Diversity antenna cable within the vehicle is shown in
Figure 12D – 5.
With reference to Figure 12D – 9, signals from the FM Diversity antenna are fed into terminal X3-A of the N3 module
(item 3 in Figure 12D – 7). These signals are amplified in a similar way the AM and FM Main antenna signals are
amplified. The output signals of the amplifier are then fed to the Diversity Antenna input conn ector of the A133 AHU via a
coaxial cable circuit 5166.
Figure 12D – 9
The antenna coil assembly comprises two antennas, one for AM signals (2) and another for FM signals (4), and these
form an integral part of the rear window glass. The FM antenna coil is also used as the rear window demister element.
The thin conductors that form each antenna are la id on the inside of the glass, and two connectors are located on the
side of the rear windo w allowing connection of the antenna coils to the a ntenn a amplifier module. The FM antenna
coil/demister is connected to body ground at X118_GP7, via circuit 1850, which also includes an RF isolation coil.

Antenna System (Coupe Only)
The antenna coil assembly comprises two antennas, one for AM signa ls and another for FM / FM2 signals, and these
form an integral part of the rear window glass. The CV8 model coupe also has a diversity antenna for augmented FM
reception. The FM / FM2 antenna coil is also used as the rear window demister element. The thin conductors that form
each antenna are laid on the inside of the glass, and two connectors are located on the side of the rear window allo wing
connection of the antenna coils to the antenna amplifier module. The FM antenna coil / demister is also connected to
body ground at X118_GP7, via circuit 1850.
The antenna amplifier module amplifies the small signals from the antenna coil assembly then transmits the amplified
signal to the radio’s antenna i nput. The module is located beneath the trim on the left han d side body rear corner garnish.
The module is connected to the au dio system head unit via a coaxial lead, circuit 5172.
A single wire lead, circuit 314, from the audio system head unit provides the +12 V supply to the antenna amplifier
module for its operation. The modu le is grounded through its case to the vehicle body. To prevent interference, it is very
important that the module and coaxial lead are grounded securely.

Figure 12D – 28
The Audio Systems fitted to the MY2003 VY and V2 Series vehicles have modern ampl ifiers that deliver high po wer and
are internally protected against short circuits and connection to voltage sources.
Level 3 model vehicles feature a high power 4 x 30 W RMS amplifier that drives 2 ohm speakers in the doors and
tweeters in the instrument panel. Two subwoofers driven by a separate 2 x 40 W RMS amplifier are fitted to the parcel
shelf to increase the frequency resp onse of the system. Other models have 4 x 20 W RMS amplifiers. Speakers in these
vehicles are 4 ohms for the doors and 2 oh ms for the tweeters. The speaker circuit for Sedans and Wagons is ill ustrated
in Figure 12D – 27, while the circuit for Utiliti es and Coupe models is illustrated in Figure 12D – 28.
All Audio Systems have a Distortion Limitin g circuit. This circuit, when turned on, automaticall y limits the volume level to
the point where distortion begins. The amount of distortion will depend on the amount of bass in the music. Listen ers who
find that the music does not play loud enoug h with the distortion limiting circuit activated can either:
• reduce the amount of bass, or
• turn the distortion limiting off using the instrument cluster MFD (refer to Section 12C, 1.8 Customisation Mode –
Audio Distortion Limiting in the MY 2003 VY and V2 Series Service Information).
Entertainment System Page 12D–34
Page 12D–34
Damaged speakers and wiring may not cause a failure when played at low volume levels. At low volume the amplifier
may cope with the additional load caused by the damage. Problems may only become obvious when playing at loud
volume levels. Typical symptoms will be
• one speaker dropping out,
• two speakers dropping o ut, or
• all speakers dropping out.
When the amplifier has cooled, the output may resume from the affected speaker or speakers.

Subwoofer Amplifier
Figure 12D – 30
Level 3 models are fitted with an auxili ary amplifier to improve the low frequency output of the system using two parcel
shelf mounted subwoofer speakers. The unit is a two channel, high powered design that features self-protection circuitry
to stop overload in the event of damage to wiring or speakers, or high temperatures. Signal inputs to the amplifier are
taken from the corresponding left and right rear door sp eakers, as per the system diagram, and the signals are then
combined to produce a mono output.
Output gain can be varied by turnin g the small adjuster mounted on the end of the casing at the opposite end to the
connector. The centre position is the default setting. From the centre position the subwoofer effect can be increased by
6 dB or decreased by 3 dB from the factory setting for customers who prefer more or less subwoofer effect. A 10 Amp
fuse mounted in the end of the unit will protect the wiring in event of an internal amplifier failure.
