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.

The orange symbols represent the possible optional
equipment. If a relevant option is missing, simply
follow the route indicated by arrows to close the
MOST ring.

MMI Basic Plus
As an option, the MMI Basic system can be
equipped with additional functions in the radio and
sound field in the form of a "Plus" version.
This includes, for example, a TP Memo function,
which enables the recording of traffic
announcements for a duration of eight minutes in
total.
A programmable recording period can be used to
provide up-to-date traffic announcements before
starting a journey. Stored traffic messages are
automatically deleted after six hours to ensure that
they are always up-to -date. Instead of the integrated
amplifier, the standard sound system with its own
digital sound package control unit J525 will be used
as standard as of this MMI version.
The internal amplifier can be deactivated via coding
in this and later MMI versions.

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.
