New identity
As is already the case with the Audi A8 ‘03 , if a
control unit is stolen, it is no longer necessary
(for safety reasons) to also replace the remaining
control units, which are integrated in the
immobiliser.
In this case, the "New Identity" function must be
used for the control unit for access and start
authorisation and the engine control unit.
It is only a matter of installing a new lock set before
using the "New Identity" function.
The switch for access and start authorisation E415
reads in the key code in electronic form only.
The hinged bit coding is not evaluated signal.
The ignition switch is not par t of the lock set for this
reason.
Component protection
As is already the case with the Audi A8 ’03, the
Convenience and Infotainment control units are also
integrated within the "Component protection" safety
system.
As a result, these control units must be adapted to
the specific vehicle once they have been installed.
The data bus diagnosis interface is integrated into
the "Component protection" function for the first
time. Since component protection works via a
number of control units, the Startup menu in
"Guided fault-finding" is not assigned to any one
control unit and can be found directly under the
self-diagnosis systems.

Multimedia Interface (MMI)
Equipment versions
As in the current Audi A8 ’03, the MMI operating
concept is now also integrated as standard in the
new Audi A6 ’05. Data is transferred between the
individual Infotainment control units via MOST bus
technology and the process is technically identical
to the Infotainment system in the current
Audi A8 ‘03. Driver-relevant functions, such as
on-board computer or navigation, are displayed in
the centre display of dash panel insert J285.
Selected functions for the telephone, radio and
CD control and volume control can be operated
using the multi-function steering wheel.Unlike the current Audi A8 ‘03, several versions of
the control unit for the front display unit J523, the
master control unit in the optical Infotainment bus,
are installed in the Audi A6 ´05, depending on the
optional equipment selected.
The Basic, Basic Plus and Basic Navigation versions
have the same hardware platform, which is
expanded to include the required optional extras.
The MMI High version, on the other hand, uses the
same hardware as the current Audi A8 ‘03.
Furthermore, the data bus diagnosis interface J533,
which assures communication with the other
networked components in the vehicle, is connected
to the MOST bus.
Infotainment
Note
Information on the MOST bus can be found in
the SSP 286 – New data bus systems,
LIN, MOST, Bluetooth.Reference
For information on the Infotainment system
with optical data transfer, please refer to the
SSP 293, Audi A8 ’03 – Infotainment.

MMI Basic Plus
As an option, the MMI Basic system can be
equipped with additional functions in the radio and
sound field in the form of a "Plus" version.
This includes, for example, a TP Memo function,
which enables the recording of traffic
announcements for a duration of eight minutes in
total.
A programmable recording period can be used to
provide up-to-date traffic announcements before
starting a journey. Stored traffic messages are
automatically deleted after six hours to ensure that
they are always up-to -date. Instead of the integrated
amplifier, the standard sound system with its own
digital sound package control unit J525 will be used
as standard as of this MMI version.
The internal amplifier can be deactivated via coding
in this and later MMI versions.

MMI High
The MMI High comes with the 7" colour display.
The standard equipment of the Top system in
Audi A6 ‘05 Infotainment includes an RDS dual-
tuner, the standard sound system and a 6x CD
changer in the glove compartment. As an optional
extra, this MMI version is also available with DVD
navigation, which is already used in the current A8
‘03, as well as the voice operator system with the
voice input control unit J507 as a plug-in module of
the radio module R.
Only in this MMI version can drivers choose
between the fixed telephone module and the mobile
baseplate. The well-known analogue TV tuner R78 is
also available at present as an optional extra.

If you order the Audi A6 ´05 with the MMI versions
Basic, Basic Plus or Basic Navigation, the
functionalities like sound system or a CD-based
navigation module are integrated into the control
unit for front information J523, depending on the
vehicle equipment. The control unit for front information J523 is
installed in the glove compartment in the standard
version.
The "High" version, which was adopted from the
current Audi A8 ’03, is located behind the display
unit for front information J685, the colour MMI
display.
