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.

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.
