Infotainment control unit holder
In the new Audi A6 ’05, the control units responsible
for Infotainment are mainly stored in a compact
holder behind the left wheel cut-out in the boot.
Only the control unit for front information J523 is
installed in the dash panel, either in a visible
position in the glove compartment (Basic version) or
behind the glove compartment (High version). The
dual-band compensator, the mobile phone
amplifier R86, is fitted on the rear right wheel well.
Reference
Please refer to the relevant Workshop Manual
for details of the exact individual installation
positions.

Standard sound system
If the optional Standard sound system is selected,
the vehicle will not have the 2x20-watt amplifier
module in the control unit for front information
J523. This sound system has an external 7-channel
DSP amplifier, the digital sound system control
unit J525, which is integrated into the MOST bus.
It controls the three-way systems in the front doors,
the two subwoofers in the front doors, the 2-way
systems in the back doors and the centre
loudspeaker in the dash panel. The standard sound
system comes as standard in the MMI versions
Basic Plus and MMI High.

BOSE sound system
The new Audi A6 ´05 comes with a BOSE sound
system, which mainly comprises components from
the current Audi A8 ‘03. The division of the
subwoofer function into two individual subwoofers
integrated into the front doors means that the
well-known 7-channel DSP BOSE amplifier must
provide an additional output for the second
subwoofer driver in the front right-hand door. The
line-out output of the amplifier is used for this
purpose. This output signal feeds an external 100-
watt driver, which is integrated into the subwoofer
in the front right-hand door.
The current BOSE amplifier is replaced by a new
development with the launch of the Avant.
All eight drivers for the BOSE sound system are
then integrated into this new Avant amplifier.
Given this, it will be impor tant to note the exact par t
numbers and the related model year when replacing
components of the BOSE sound system in the
future, so that the functionality of the BOSE sound
system is not lost!
BOSE sound system diagnosis
Diagnosis of the BOSE sound system is also
performed using the address word 47 in the
VAS tester.
A basic setting is not required.
The available actuator tests can be performed either
selectively or sequentially.
The AudioPilot microphone, which is integrated into
the BOSE sound system, can be used to absorb
the acoustic pressure produced during the
loudspeaker actuator tests and output this on the
VAS diagnosis tester as a voltage signal.
If a voice operating system is installed, the
microphone for this is also included in the test.
The technician must then compare this voltage
reading with a default reading set at the factory and
evaluate the completed test as either OK or Not OK.

Available telephone systems
Two different telephone systems are available
ex-works for the new Audi A6 ´05.
Firstly, there is the fixed system with Bluetooth
operator handset, with which you may be familiar
from the current Audi A8 ´03, but which can only be
ordered with the High version of the MMI. Secondly, there is the newly developed mobile
baseplate. This mobile baseplate has a similar
control unit architecture and functionality to the
system used in the Audi A3 ´04.
However, it has now been incorporated into the
MOST bus for Infotainment.

Handsfree operation
The telephone transmitter and receiver R36 sends
the signals for handsfree operation (Voice, Phone
Mute, etc.) via the MOST Infotainment bus to the
relevant sound system, which is either integrated
into the control unit for front information J533 or
the independent digital sound system control
unit J525. Here, the digital data is converted into
analogue data and is output on the loudspeaker.
Echo and noise compensation
The telephone transmitter and receiver R36 is fitted
as standard with a DSP-based echo compensation
system. If the optional voice operating system is
also ordered, the echo and noise compensation
function of the control unit for voice input J507 is
used. Among other things, this results in an
improved handsfree quality, even for the passenger.
