The key has a mechanically coded hinged bit for the
lock cylinder in the driver’s door and the tailgate/
boot lid. The transponder function is integrated into
the electronics and also works without a battery.
An integrated battery powers the electronics for the
radio remote control and Advanced Key functions.
A new feature here is the bi-directional data
exchange between the radio-control key and the
control unit for access and start authorisation via
the antenna for central locking and anti-theft
warning system R47. This is used to transfer the
status of the central locking system into the key.
If a button outside of the function range of the key
is pressed, the LED integrated in the key shows the
lock status of the vehicle. The lock status displayed
is always the status, which was achieved using this
key when central locking was last actuated.
If the vehicle is opened or locked in the interim
period using a second key, this does not change the
lock status in the first key.
Furthermore, the radio frequency is changed from
433 MHz to 868 MHz for the first time in many
countries. This radio frequency is ideal for data
communication between vehicle keys and the
control unit.
Since this frequency can only be used for very short
transmission pulses, any interference from
long-term radio transmitters, such as baby phones,
wireless headsets, etc. is eliminated.

The control units for seat adjustment can be used to
set up to 8 individual seat positions for an
electrically adjustable seat. The seat positions can
be stored in memory and can be set again if
necessary using the memory keypad or by entering
a radio code.
Installation position
The control units for seat adjustment are located in
the floor area under the driver’s and passenger’s
seat.
The control unit can be used both for the driver’s
seat and for the passenger’s seat by assigning
a PIN code in the connecting plug.
The unlearned/uncoded control unit is thus coded
automatically for either the driver’s seat or
passenger’s seat installation position – depending
on the pin – when it is first connected to the seat.
This operation can only be performed once, but can
be released again by means of the diagnostic
function (in the Conditioning menu item).
Diagnosis
The following diagnostic functions are available
under the address words 36 Seat adjustment,
driver’s side and 06 Seat adjustment, passenger’s
side:
– Read measured-value blocks
–Coding
–Actuator test
–Adaptation

Convenience electrics
Function
The control unit for seat adjustment powers the
positioning motors in the seat directly using its load
outputs. The position detection function of the
positioning motors is implemented using hall
sensors. The driver’s-side door control unit reads in
switch information from the operator unit for
memory, driver’s seat E97 as voltage-coded
information and sends this via CAN Convenience to
the control unit for seat adjustment with
steering-column adjustment memory J136.
The control unit for seat adjustment with
steering-column adjustment memory reads in
information from the switch for fore-and-aft and
height adjustment, driver’s seat E61, the switch for
backrest adjustment, driver’s seat E96 and the
switch for tilt adjustment, driver’s seat E222 directly.
The driver’s-side door control unit J386 reads in the
button information "Seat memory emergency-Off"
and supplies this discretely as well as in the form of
a CAN Convenience message to the control unit for
seat adjustment with steering-column adjustment
memory J136. Comfort functions, such as seat
symmetry positioning and comfort side view as well
as radio code allocation to a memory location, are
implemented using settings in the Multimedia
Interface (MMI).

Seat symmetry positioning
The "Symmetry positioning, driver’s seat/
passenger’s seat" option, which is available in the
MMI, can be used to move the passenger’s seat into
a symmetrical position in relation to the driver’s
seat. The MMI sends a corresponding instruction to
the driver’s seat control unit via the
CAN Convenience bus. The control unit then sends
the current seat position and a control instruction to
the passenger’s seat control unit, which positions
its motors accordingly.
Comfort side view
The "Comfort side view" option moves the
passenger’s seat into a position that hides the
vehicle’s B-pillar, thereby ensuring that the driver
has the best possible view out of the vehicle.
The function can be selected via the MMI, where the
signal is transmitted in the same way as for the
"Seat symmetry positioning" function.
Memory retrieval
Radio code memory
Memory settings are retrieved using the radio code. Personal button memory
Settings are retrieved and stored using the memory
buttons in the door panel.
The stored memory settings can be retrieved in
the following ways.

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.

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
