Audi Q3: Radio Installation Instructions

Retrofitting Radio Systems

General Information

Before installing radios and telephone systems (radio systems), disconnect the negative terminal of the Battery -A-. Refer to →Electrical Equipment; Rep. Gr.27.

Use the applicable wiring diagrams. Refer to → Wiring diagrams, Troubleshooting & Component locations.

Secure wiring harnesses to cable ties. Wrap connector couplings with foam to prevent rattling.

Follow the manufacturer operating and installation instructions for cell phones, radios and antennas. Refer to Operating Instructions.

• Battery -A-, Disconnecting and Connecting. Refer to →Electrical Equipment; Rep. Gr.27.
• Wiring diagrams, fuse assignment and component locations. Refer to → Wiring diagrams, Troubleshooting & Component locations.
• Trim Panels, Removing and Installing. Refer to →Body Interior; Rep. Gr.70.
• Standard Devices, Removing and Installing. Refer to →Communication; Rep. Gr.91.
• Antenna Wires, Repairing. Refer to → Electrical Equipment General Information; Rep. Gr.97; Wiring Harness and Connectors, Repairing; Antenna Wires, Repairing.
• Wiring Harnesses, Repairing. Refer to → Electrical Equipment General Information; Rep. Gr.97; Wiring Harness and Connectors, Repairing.

Transmitting Power and Possible Component Locations

Audi permits the installation and operation of radio systems, as long as the transmitting power at the antenna base (listed in the tables for the respective vehicle model) is not exceeded. For required antenna component locations and transmitting powers, refer to the tables. Refer to → Chapter "A1 from MY 2011 through MY 2012".

The limits set forth in VDE 0848 Part 2 (maximum permissible field intensity to protect persons) must also be maintained even through reduction of transmission output.

Power Supply

When retrofitting radio systems in the vehicle, the Battery -A- is used to connect the positive and negative wires.

The wiring harness must also be made:

• Positive wire: 2.5 mm strong red wire
• Negative wire: 2.5 mm strong brown wire
• Terminal 15 wire: 1.5 mm strong black wire

The positive wire should be equipped with a fuse next to Battery -A-. Attach a fuse panel next to the Battery -A- for this. Cover the positive and negative wires with an insulating hose. Attach the appropriate cable shoes on the battery side. Proceed according to the radio system operating instructions on the device side. Refer to Operating Instructions.

Route the additional wiring harness separately from the vehicle wiring (distance greater than 10 cm).

  Note

Crossing the standard wiring is better than routing it parallel.

Antenna and Wiring

A shielded wire must be used between the radio and the antenna. Shielding must be grounded on the device side and antenna side. At the same time, there must be a proper and stable ground connection for the antenna base wire to the vehicle body.

The transmitting system must only be used when shielded to avoid sheath waves in antenna wiring. To ensure the radio system is tuned and operating correctly, an output/performance test is recommended.

It is only possible to have "on glass" antennas on vehicles without tinted glass.

Other Auxiliary Installations

The installation of other electronic equipment such as business equipment (TV, FAX) or household equipment (electrical cooling box) is only permitted if these devices are marked with a CE or e-sign. Power must be supplied by a separate wiring harness equipped with a fuse.

Transmitter Power Output and Antenna Component Locations

Q3 from MY 2015

eff. = effective transmission output

PEP = maximum carrier power (Peak Envelope Power)

  WARNING

If radio systems are installed with a higher output or with an antenna that differs from the items named above, the vehicle operating permit may be void.
