The control unit for front information J523 includes
an enhanced TP recording system in the Standard
Plus and Standard Navigation versions. This is a
programmable traffic programme recording
function, which is possible via the MMI operating
system.
Two different start times can be set. The traffic
broadcasts that are received are recorded for a
duration of 2 hours from the relevant start time.
This setting remains unchanged until the timer
function is switched off or the programmed times
are changed. A memory with a recording capacity of
8 minutes is available for the recording. When the
memory is full, the oldest messages are overwritten.
The CD-based navigation function is integrated as
an optional module in the display and operating
unit for front information J523.
If this equipment is installed, the vehicle comes with
the antenna module R50, the antenna for
GPS navigation in the top area of the rear window
(see Chapter Antenna systems). This antenna
delivers the GPS signal. If the mobile baseplate was
also requested, the vehicle has a roof antenna
(antena for radio, telephone, navigation R52), which
supplies the GSM and GPS signal. All other input
signals are only supplied by networking the relevant
control units. Playback of the stored messages can
also be controlled via the MMI. It is possible to
select here whether you want to play the entire
sequence or only one particular message.Functional features of the standard navigation
function:
– Position-finding through interactive destination
entry/selection
– Interactive journey planner/management with
stop-off destinations
– Selection of route options
– Route guidance (acoustic and optical via arrows
in display on dash panel insert J285)
– Dynamic route guidance via RDS TMC and online
data
– Audible navigation directions via digital sound
package control unit J525
– Storage and management of destinations
– Output of position data to the CAN bus
(e.g. for Audi telematics)
– Search for imported destinations from the
address book
Navigation input signals from the vehicle network:
Distance signal from control unit for ABS with
EDL J104, signal from reversing light switch
Output signals to the vehicle network:
GPS time including date, voice output to the
digital sound system control unit J525

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.

Standard sound system diagnosis
The diagnosis process is effected via address
word 47 as in the case of the series equipment,
however, the separate control unit for digital sound
system, J525, is now addressed. In addition to
reading the measured-value blocks and the fault
memory for all loudspeaker channels involved,
selective actuator tests are also available.
The digital sound system control unit participates in
component protection.

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.

The telephone transmitter and receiver R36 is fitted
as standard with a Bluetooth module.
In principle, the Bluetooth functionality
is always available, even if a mobile phone holder is
not connected. For reasons of electromagnetic
compatibility, Bluetooth is only active at present
when the mobile phone is inserted into the relevant
holder. The phonebook stored on the mobile phone
SIM card is read into the memory of the Telephone
transmitter and receiver R36 whenever the mobile
phone is inserted. Mobile-internal phonebooks
cannot be read in because the data formats differ
from model to model. The mobile baseplate is operated via the MMI in the
"TEL" menu. The telephone holder R126, which is
required for whichever type of mobile phone is to be
used, is available from the Parts Service. As you may
already know from the introduction of the new
mobile baseplate in other model series (Audi A3, A4,
TT), this mobile phone holder no longer has a
connection cable. It is connected to the telephone
transmitter and receiver R36 via a contact panel.
Voice operation
The new mobile baseplate can be voice-operated
using the operating unit in the steering wheel E221.
The handsfree volume can also be set using the
multi-function steering wheel and names or
telephone numbers can be dialled in the
phonebook. The operating unit in the steering
wheel E22 1 passes the data si gnals fo r this on to the
steering column electrics J527 as LIN signals.
This control unit converts the data into CAN
messages and transfers these messages to the data
bus diagnosis interface J533 on CAN Convenience.
Here, the digital data messages are converted into
MOST data records and are passed to the telephone
transmitter and receiver R36 via the MOST ring.
The adapter set always includes a Push-to-talk
button (PTT), which enables voice operation even
without the multi-function steering wheel option.
This button is included on every available mobile
phone adapter.
The PTT button has different functionalities,
depending on the MMI used:
– MMI High: Accept/Hang up
– MMI Basic/Basic Plus/Basic Navigation:
Accept/Hand up and also
Activate internal voice operation of the
telephone transmitter and receiver R36.
This internal voice operation function is only
available in the MMI Basic versions. Voice operation
in the MMI High version is implemented via the
optional control unit for voice input J507.

This illustration depicts the service handset for the fixed telephone
installation (MMI High) and the alternative universal mobile
baseplate with the mobile adapter. A vehicle cannot be fitted with
both systems!

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.
