2005 AUDI A6 display

Downloaded from www.Manualslib.com manuals search engine 40
The control unit in dash panel insert J285 is
available in two variants.
The High-Line variant with colour display only
comes in vehicles with adaptive cruise control.
As in the A8 '03, the anti-drive-off feature and
gateway are no longer integrated into the dash
panel insert.
The handy position of the rotary light switch has
meant that the indicator lights for dipped beam
headlight, fog light and rear fog light could also be
fitted directly in the rotary light switch.
Likewise, the buttons for instrument lighting, the
auto-check system and the daily mileage counter
are now positioned to the right, next to the dash
panel insert, in the button module (operating
buttons for dash panel insert E493).
Convenience electrics
Lamp failure
If an exterior lighting lamp fails, a symbol appears
in the central display indicating which lamp has
failed. If you now press the Check button, the failed
lamp is also described by a text message in the
central display.
Outside temperature indicator
The instrument cluster evaluates both the
temperature sensor for outside temperature G17
and the outside temperature signal from the
Climatronic control unit J255. The lower of the two
values is displayed.

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
Standard equipment in the new Audi A6 includes
MMI Basic with the MMI operating concept, a
7" monochrome display (J685) in the dash panel
inser t as well as an integrated, analogue radio tuner
and 4x antenna diversity, CD drive and a 2x20-watt
amplifier.
In principle, these drivers are available in all
versions of the control unit for front
information J523.
In the MMI Basic version, the loudspeakers that are
integrated into the front doors are connected
directly to the control unit for front
information J523.
If the Standard Sound System or BOSE option is
installed, this internal amplifier is deactivated via
coding. The loudspeakers are then connected to the
relevant digital sound package control unit J525.Digital tuner technology will be available in the
Audi A6 at a later date. Depending on the market in
question, a satellite radio receiver or a receiver for
terrestrially emitted, but digitally coded
transmissions will then be available.

equipment. If a relevant option is missing, simply

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 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.
