General information


NOTES:
- When a new model is introduced, a new generation of radio with updated design and technology is installed.
- Should a problem arise, it is important that the technician understand the function and operation of the stereo system. For additional information See radio operating manual.
- When troubleshooting, repairing, or replacing the stereo system, refer to the appropriate wiring diagram, as well as installation instructions supplied with replacement parts.
- Use only authorized Audi replacement radios and/or parts to ensure proper system performance and optimum reception.
- Both active (amplified) and passive (non-amplified) speakers are used.
- Power, battery positive voltage (B+), is supplied to the radio via a fuse in the fuse panel
- The radio anti-theft coding is fixed (cannot be changed) and must be re-entered whenever the radio power supply (B+) has been disconnected.
- A rear antenna amplifier is installed in each of the 0-pillars (left-side 0-pillar: AM and FM antenna amplifier; right-side 0-pillar: FM antenna amplifier only).


When installing a radio, note the following:
- Radio connectors provided in the vehicle are intended for use with original Audi radios.
- Aftermarket radios with other connector types must use an adapter cable.
- When connecting the radio, make sure that the vehicle speed signal wire is not short-circuited, or there may be related malfunctions in other vehicle systems.
- Connecting the vehicle speed signal wire to an aftermarket radio may also cause other vehicle systems to malfunction.
