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.

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 Navigation
The MMI Basic Plus is available on request with a
basic navigation function. For this purpose, a
navigation module is integrated into the
information control unit J523. Optical route
guidance is provided on the central display in the
dash panel insert. The destination is entered using
the MMI operating system with its central knob/
pushbutton.
Audible directions for route guidance are also
output via the sound system.
The data required for navigation is read in via the
integrated CD drive.

The orange symbols represent the possible optional
equipment. If a relevant option is missing, simply

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.

Antenna systems
The antenna system in the new Audi A6 ´05 is
integrated as a module in the top area of the rear
window, to the left and next to the third brake light,
on the right.
The modules are responsible for the various
s y s t e m s, e . g . re m o t e c e n t ral lo ck i n g , rad i o , T V o r t h e
radio receiver for the auxiliary heater.
Only the modules that are required for the
requested optional extras are installed.The table shows the relevant modules for the
available vehicle equipment. These are indicated for
the various, worldwide country versions.
The modules "DAB" and "SDARS" relate to the digital
radio systems, which will be available later and are
based on either a satellite-controlled system
(SDARS) or a terrestrial system (DAB).

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
