Mmi Basic - Audi A6 2005 - Electrics Service Training

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
insert 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.
