Cellular Telephone And Two-Way Radios, Operating Instructions

WARNING: This page is about a different variant/trim than selected.

Cellular Phones and Portable Two-Way Radios with Separate External Antenna

Radio remote controls (e.g. for garage door opener) and wireless units (e.g. keyboard or PC mouse) may only be used in the vehicle if the transmitted output is maximum 100 mW.
Please follow exactly the operating instructions and installation instructions of the manufacturer of mobile telephones, radio-based devices, and antennas.
The devices' optimal range will only be reached with an exterior antenna.
When telephone and two-way radio systems are installed properly there is no danger to safety systems such as the ABS or the airbag. A prerequisite is however that there has been no intervention in their installations. Parallel wiring to such systems must be avoided.
Excessively high electromagnetic fields can arise if mobile telephones and radio devices, with or without an incorrectly installed exterior antenna, are used. In such a case, damage to health and interference with vehicle electronics cannot be ruled out.

Radios/Telephones with a Transmitted Output Above 10 Watts, Prerequisites

The transmitted output on antenna base (see manufacturers designations) must not exceed the relevant maximum values.
You may not use antenna locations other than those shown in the table.

Transmitted output and antenna fitting locations table, refer to CELLULAR TELEPHONE AND TWO-WAY RADIOS, TRANSMITTED OUTPUT, ANTENNA INSTALLATION LOCATIONS .

Performing Repairs

Disconnect the battery before starting. Refer to [For transmission(s) 0A4, 02E, 09G, 02Q] [For engine(s) CBTA, CJAA, CBUA] Removal and Installation

Use the most current wiring diagram.

Trim panels, removing and installing, refer to Removal and Installation .

Follow the manufacturer operating and installation instructions for cellular telephones, two-way radios and antennas. Refer to the Operating Instructions.

Secure wiring harnesses to cable ties. Wrap connectors with foam to avoid rattling noises.

Transmitted Output, Possible Installation Locations

Volkswagen permits the installation and operation of radio units, 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 (maximum permissible field intensity to protect persons) must be maintained even, if necessary, through reduction of transmission output.

Voltage Supply

When retrofitting a radio, the battery is used for connection the positive and negative wires.

The wiring harness must be manufactured additionally:

Power supply (+) red wire with 2.5 mm ² cross section
Power supply (-) brown wire with 2.5 mm ² cross section

The positive wire must have a fuse which must be located very close to the battery. Attach the fuse panel 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.

Some telephone systems and radios also need terminal 15. In this case, route a black wire, 1.5 mm² cross section, from the transmitter/receiver unit to terminal 15a.

When installing, make sure wiring connections are not routed parallel to standard wiring.

Antenna and Wiring

Use a shielded wire between the transmitter and the antenna. 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.

The transmitting system must only be used when shielded to avoid interference in antenna wiring. To ensure the system it is tuned and operating correctly it is recommended that an output/performance check is carried out.

Other Auxiliary Installations

Installing other electronic equipment such as a TV or a fax machine or household equipment, such as an electric cooler box, is only permitted if they have the "CE mark" or a "e-mark". This applies only to Europe.

Voltage supply is performed via a separate wiring harness and secured by a fuse.

Repairing Antenna Wires

A new repair concept has been developed for repairing antenna wires. Instead of a complete antenna wire, connecting wires of different lengths and various adapter leads are now available as replacement parts.

Repairing antenna wires, refer to [For transmission(s) 0A4, 02E, 09G, 02Q] [For engine(s) CBTA, CJAA, CBUA] ANTENNA WIRE REPLACEMENT .
