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

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

Sound systems
Different sound system versions are available for
the new Audi A6 ´05. A general feature of the
systems is the two subwoofers integrated into the
front doors. A central subwoofer is not installed in
the rear storage area in the Audi A6 ’05 – a standard
feature in other model series.
The base frequencies, which cannot be localised for
the human ear, are amplified by the two tuners in
the doors and are used to round off the audio
pattern in the interior of the vehicle. This saves
space in the rear area, which increases the boot
volume and leaves more room for installing other
control units.

The new Audi A6 ´05 is equipped with a two-way
loudspeaker system in the front doors as standard.
The related amplifier with two 20-watt drivers is
integrated into the control unit for information J523.
Diagnosis of the standard amplifier module is
performed using the address word 47 in the
VAS diagnosis tester. The possible diagnostic
functions are contained in the list of diagnostic
options for the control unit for front information
J523 on page 78 in this chapter.
