Please note: An integrally mounted screen aerial may give rise to increased multipath

MULTIPATH DISTORTION / MUTING

distortion or spurious muting of the audio output. This is normal and to be expected.
The use of an externally mounted rod aerial may reduce or possibly eliminate such
problems.

Most screen aerials require a 12 volt supply to operate correctly. Please check that this
has been connected the +12 volt antenna wire of your radio. If you are in any doubt of
this connection please contact the vehicle dealer or Goodmans installation helpline.

IMPORTANT: Do not forget to remove the transit scr ews on top of the unit.

Before removing the fixing cage and installing the unit.
Failure to do so will result in the CD not playing.

PLEASE READ THIS BEFORE CONNECTING THE
PLAYER TO THE VEHICLE

Prior to final installation carry out a sound check. If high distortion or intermittent sound
is experienced it is possible that the wiring to the car’s electric is poor, or that the battery
needs recharging.

IMPORTANT NOTES

If the battery and its charging circuit are OK, then rewire the red fused wire of the player
directly to the positive terminal (+) of the car battery. Car accessory shops stock the
connector blocks and the 15 Amp cable which may be necessary for extending the fuse
wire connection.

EARTHING: Make sure that the black wire on the wiring harness is connected to a good
earthing point on the car. If the chassis of the car is used as an earthing point, make sure
that the paint is scraped clean from the metal work before attaching the wire to it. It is
preferable to connect the black earthing wire directly to the negative terminal (–) of the
car battery.

WARNING: POLARITY.....

This model is only suitable for use in vehicles which have a negative earth system.
e.g.: The negative terminal of the car battery is connected to the chassis.

Connecting The Speakers And Power Cables

Before you wire your system, disconnect your vehicle battery’s positive (+) cable.
This helps prevent damage in case of a short. When you complete the wiring, reconnect
the battery cable and test your car stereo.

Note: Check with your vehicles handbook or dealer before disconnecting the vehicle

When connecting your car stereo’s black ground wire, be sure to connect the wire to a
metal part of your vehicle or preferably to the negative (–) terminal of the car battery.

PRECAUTIONS AND MAINTENANCE

• This unit is designed for negative ground 12V DC operation only. The equipment can
be used safely, if the negative terminal of the battery is connected to the vehicle metal
work.

• Do not use speakers of impedance less than 4 ohms; and do not allow the speaker
wires to be shorted together when the unit is switched on.
Otherwise it may overload or burn out the power amplifier stage.

• If the car interior is extremely hot, as after being parked in the sun, do not use the
player until the car has been driven for a while to cool off the interior.

IMPORTANT

After installing the unit, switch on the power to the unit and press the RESET button using
a pen or thin match stick.

RESET

Caution Vauxhall owners:

Vauxhall do not follow normal ISO wiring convention which may cause Goodmans radios’
to lose the radio preset memories each time the ignition switch is turned off. To prevent
such occurrences swap over the Red ignition and Orange Memory wires in the bullet
connectors attached to the wiring harness of the car radio.

This radio contains two separate power amplifiers, to prevent possible damage to these
amplifiers please ensure:

1) The vehicle chassis is not used as a loudspeaker earth (–ve return).

2) Front and Rear loudspeaker connecting wires are not joined together.

3) Any wires not used when completing a two speaker installation are fully insulated.

4) The memory wire (Orange) is connected to a permanent +12V supply.

5) The power wire (Red) is connected via the ignition switch of the vehicle.
