1.1.1 Notes on radio service installation
• Radios with different types of connector must be installed us‐
ing adapter wires.
• When connecting vehicle speed signal wire (GALA function),
take particular care to avoid short circuits as otherwise vehicle
malfunctions could occur (e.g. engine management system).
• Vehicle malfunctions may also occur if the vehicle-speed sig‐
nal wire is connected to radios supplied by other manufactur‐
ers.
• The use of radios supplied by other manufacturers may affect
the aerial amplifier. Genuine Audi radios have a “remotely
powered” aerial, i.e. the aerial amplifier receives its voltage
supply via the central core of the aerial cable. Use is therefore
to be made of remote power supply adapter from the Audi
range.

1.16 Function test of BOSE microphone (in‐
terior microphone)
As of MY 03, a microphone is installed with BOSE Sound radio
units for monitoring interior noise (Audiopilot). This is connected
directly to the BOSE amplifier. When noise increases in the inte‐
rior, the amplifier (Audiopilot) automatically adjusts the volume
according to the specified pattern.
When the radio is switched on, the BOSE amplifier checks the
voltage supply level of the microphone. If the result is OK, there
is no reaction.
If the microphone, however, is not installed, three short tones are
emitted three times.
In the case of a short circuit, three short tones are emitted.
Function test of microphone:
– Switch on the radio and tune into a station.
– Tap lightly on the microphone for a while
♦ Coupe: on the top centre of the dash panel insert.
♦ Roadster: below the ashtray
The volume of the radio station tuned to should increase audibly.
