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

Mobile baseplate diagnosis
The mobile baseplate is diagnosed as standard
using the address word 77 in the VAS tester.
A selective or sequential actuator test can be
performed to check the output of the audio signal to
the relevant sound system, radio mute operation,
and whether or not a switched-on phone was
detected.
