Procedures

Performing Repairs, Notes

Before starting repair work, batteries must be disconnected.

Use valid current wiring diagram.

Observe manufacturers operating and installation instructions for cellular 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 systems, as long as the transmitted power on antenna base, listed in table, is not exceeded. For prescribed antenna locations see table.

Limit according to VDE 0848, part 2 (max. permissible field intensity to protect persons) must be maintained even, if necessary, through reduction of transmission output.

Voltage supply
When retrofitting 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 read wire, 2.5 sq.mm cross section
- Voltage supply negative via brown wire, 2.5 sq.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 battery. Both wires must be encased in an insulating hose.

suitable connections must be attached on battery side.

Proceed on unit side according to operating instructions.

The additional wiring harness must be routed separately from vehicle wiring, distance must be at least 10 cm.

NOTE:
- For some telephone systems (if applicable) and radio communication units an additional terminal 15 (ignition) is necessary. Then, a black wire connection of 1.5 sq.mm cross section must be connected from transmitter/receiver unit to terminal 15a.
- When installing, make sure wiring connections are not routed parallel to standard wiring.

Antenna and antenna wiring
A shielded wire must be used between transmitter/receiver unit and antenna. Shielding must be grounded to unit and antenna.

At the same time, make sure Ground (GND) connection of antenna base wire to vehicle body is correct and continuous.

The transmitting system must only be used when shielded to avoid interference in antenna wiring. To be sure, system must be checked and tuned via performance test.

Other auxiliary installations
The installation of further electronic equipment like business equipment (e.g., TV, FAX) or household equipment (e.g. electrical cool box) is only permitted if these appliances are marked with a CE or e-sign (Europe only).

Voltage supply must also be routed via separate wiring set and secured by fuse.
