Volkswagen Golf / Golf GTI / Jetta. Manual — part 1202

91-107

When telephone and two-way radio systems

are installed properly there is no danger to
safety system e.g. ABS or airbag. A
prerequisite is however that there has been no
intervention in their installations. Parallel wiring
to such systems must be prevented.

The use of a mobile telephone or a two-way

radio without or with an incorrectly installed
external antenna results in increased electro-
magnetic fields in the vehicle interior.

In this case detrimental affects to health or

malfunctions of vehicle electronics could be the
consequence.

Installation and operation of

radios/telephones with a transmitted output
above 10 watt for the radio communication
services listed in the table is only permitted
regarding the following prerequisites:

The transmitted output on point of the antenna

base must not exceed the relevant max. values
(see manufacturer's designations).

The antenna locations listed in the table must

be maintained.

Performing repairs, notes

CAUTION!

Before beginning repairs on the electrical
system:

Switch off all electrical consumers.

Switch ignition off and remove ignition
key.

Disconnect negative ( - ) battery terminal.

When disconnecting and reconnecting
battery terminals, observe all applicable
Notes and torque specifications, as well as
instructions on performing OBD program
and electrical system function checks as
specified

Observe manufacturer's operating and

installation instructions for mobile telephones,
two-way radios and antennas.

Secure wiring harnesses to cable ties. Wrap

connectors with foam to avoid rattling noises.

Transmitted output and possible installation

locations

Volkswagen permits the installation and

operation of radio units if the transmitted power
on point of the antenna base, listed in table, is
not exceeded. For prescribed antenna locations
see table.

The limiting values according to VDE 0848 part 2

(max. permissible radiation strength for personal
protection) must be adhered to by reducing the
transmitted output.

Voltage supply

When retrofitting a transmitter/receiver unit in the

vehicle, the battery is used to connect the
positive and negative wire.

The wiring harness must be manufactured

additionally:

Voltage supply positive via red wire, 2.5 mm

cross section.

Voltage supply negative via brown wire, 2.5 mm

cross-section.

The positive wire must have a fuse which must

be located very close to the battery. Therefore a
fuse holder must be secured next to the battery.
Both wires must be encased in an insulating
hose.

Make suitable connections at battery end.

On unit end proceed as per owner's manual.

The additional wiring harness must be routed

separately from vehicle wiring, the distance apart
must be at least 10 cm.

Note:

For some telephone systems and radio

communication units an additional terminal 15
(ignition) is necessary. Then a black connection
(1.5 mm cross-section) must be connected from
transmitter/receiver unit to terminal 15a.

Current flow diagrams, Electrical fault finding and

Fitting locations

Ensure wiring connections are not routed

parallel to the standard wiring.

Antenna and antenna wire

A shielded wire must be used between

transmitter/receiver unit and the antenna. The
shielding must be grounded to unit and antenna.

At the same time ensure correct and continuous

Ground (GND) connection of antenna base wire
to vehicle body.
