Communication: Overview Volkswagen Eos I

CELLULAR TELEPHONE AND TWO-WAY RADIO OPERATION

Cellular Telephones and Two-Way Radios Cannot Be Operated Within The Vehicle Without A Separate External Antenna

1. Remote controls (such as for garage door openers) and wireless devices (such as keyboard or PC mouse) may only be operated in the vehicle if the transmission power of the device is a maximum of 100 mW.
2. Follow the operating and installation instructions provided by the manufacturer of the cellular telephones, radio-based devices, and antennas.
3. The devices' optimal range will only be reached with an exterior antenna.
4. When telephone and two-way radio systems are installed properly there is no danger to safety system such as ABS or airbag. A prerequisite is however that there has been no intervention in their installations. Parallel wiring to such systems must be avoided.
5. Excessively high electromagnetic fields can arise if cellular telephones and two-way radios, 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

1. The transmitted output on antenna base (see manufacturers designations) must not exceed the relevant maximum values.
2. You may not use antenna locations other than those shown in the table. Refer to «TRANSMITTED OUTPUT, ANTENNA INSTALLATION LOCATIONS»(ref-475596-S12098982862012052300000) .

Table Transmitting Power and Antenna Locations, refer to TRANSMITTED OUTPUT, ANTENNA INSTALLATION LOCATIONS .

Performing Repairs

Before starting repair work, batteries must be disconnected! Refer to [For transmission(s) 02E, 02Q] [For engine(s) BPY, CCTA, BUB, CBFA] Removal and Installation .

Use valid current flow diagram.

To remove and install trims, refer to Removal and Installation or Removal and Installation .

Observe the manufacturer's 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, 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.

The limits set forth in 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

1. Voltage supply positive via red wire, 2.5 mm 2 cross section.
2. Voltage supply negative via brown wire, 2.5 mm 2 cross section.

The positive wire must have a fuse which must be located very close to the battery. Therefore a fuse panel 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 wire connection of 1.5 mm 2 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 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

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

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

Communications systems in the Eos include in general the radio or radio/navigation system, telephone system, antenna system, speaker systems, USB connection, CD changer, compass and sound system amplifier.

Some equipment can be obtained only as options, also not all systems are installed in every vehicle.

Note. Familiarity with the function and operation of the communication systems is essential when addressing customer complaints. For servicing or fault finding, use Vehicle Diagnosis, Testing & Information System VAS5051B.

Troubleshooting

Communication systems are equipped with OBD.

To fault find, use "Guided Fault Finding" in the Vehicle Diagnosis Tester.
