High frequency units
14Remove the instrument panel surround
and the facia top.
15Remove the two screws which secure the
speaker bracket. Disconnect the wiring and
withdraw the speaker and bracket together.
The screws which secure the speaker to the
bracket can then be removed (see
illustration).
16Refit by reversing the removal operations.
Hatchback
1The heated rear window element is used as
the radio aerial. To produce a good signal at
the radio a pre-amplifier, mounted in the
tailgate, is used.
2Remove the tailgate interior trim panel,
which is secured by eleven screws.
3Remove the two screws which secure the
pre-amplifier (see illustration). Disconnect the
wiring from the pre-amplifier and remove it.
4Refit by reversing the removal operations.
Saloon
5On these models the pre-amplifier unit is
located under the rear parcel shelf and can be
accessed from within the boot.
6To remove the unit, from within the boot,
slacken and remove the two retaining screwsthen lower the pre-amplifier out of position
and disconnect the wiring connectors (see
illustration).
7Refitting is the reverse of removal.
Estate
8On Estate models the pre-amplifier unit is
situated in the roof, just in front of the tailgate.
9To remove the pre-amplifier, open up the
tailgate then carefully release the headlining
from all the relevant trim panels and peel it
back until access to the unit can be gained.
10Undo the two retaining screws then lower
the unit out from the roof and disconnect the
wiring connectors.
11Refitting is a reverse of the removal
procedure ensuring that the headlining is
neatly fitted and correctly located behind all
the relevant trim panels.
1This Section deals with the facia-mounted
control. On models with a graphic equaliser, the
joystick fader is incorporated in the equaliser.
2Remove the instrument cluster.
3Prise out the fader surround and detach the
bulbholder (see illustration).
4Release the fader control by turning its
retaining clip anticlockwise. Withdraw it from
the facia and disconnect its multi-plug.
5Refit by reversing the removal operations.1Pull the heater control knob off its lever.
Remove the two retaining screws from the top
corners of the rear console faceplate.
2Pull off the balance and volume control
knobs. Withdraw the console and disconnect
the wiring from it.
3The console may be removed from the face
plate if wished by undoing the three retaining
screws.
4To renew the console bulbs, extract the
bulbholders by grasping with pliers and
turning them anti-clockwise.
5Refit by reversing the removal operations.
1The rear headphone relay is located behind
the facia, next to the AWS control assembly
and the speed control module (when fitted). Its
function is to mute the loudspeakers when the
headphones are plugged into the rear
entertainment console.
2To remove the relay, first remove the AWS
control assembly and (if applicable) the speed
control unit.
3Disconnect the relay multi-plug, undo its
securing screw and nut and remove it.
4Refit by reversing the removal operations.
The alarm system is available as an optional
extra. On vehicles so equipped, the alarm is
automatically set by locking the driver’s or
front passenger’s door with the key. After a
brief delay (approximately 20 seconds), the
alarm will be set off if the doors, bonnet or
tailgate are opened.
The only way to disarm the alarm system is
by unlocking one of the front doors with the
key. Even if the key is used to open the
tailgate, if the alarm is set it will go off.
