Available sound systems
The new Navigation Plus system (RNS-E) for the
Audi A3 ´05 comes with a choice of two different
sound system options. Firstly, the standard sound
system, whereby the two front channels are
amplified directly by the power amps of the RNS-E
and the other channels are amplified by the
amplifier with bass loudspeaker R44 in the rear of
the vehicle. This system has self-diagnostic
capability and all loudspeaker channels can be
diagnosed using the diagnostic tester. During the
final control tests on each channel, a fixed
frequency is output to the respective final control
element. A new feature of models with the standard
sound system is that final control tests can now be
performed on the rear loudspeakers using the "Final
control test" function of the Navigation Plus system
(RNS-E) under Address word 37 (Navigation Plus
RNS-E). These tests can otherwise only be
performed directly using the amplifier with bass
loudspeaker (on left in luggage compartment) R44.
The optional BOSE sound system does not have
selfdiagnosis capability via diagnostic tester
VAS 5051 or VAS 5052. All audio channels are
amplified by a separate BOSE amplifier. As with the
BOSE sound system in the Audi A6 and A8, this
amplifier now also features an AudioPilot
microphone. However, this AudioPilot system does
not send data from the vehicle network (e.g. engine
variant, leather or fabric seats) to the BOSE amplifier
R12. The AudioPilot system in the Audi A3 records
music and noise signals through the microphone in
the overhead module, then subtracts the "clean"
music signal and, after a frequency analysis,
amplifies the frequency ranges affected by noise to
a greater degree than the unaffected frequency
ranges.
