The control unit is only installed together with the
Advanced Key option.
It is located at the right of the dash panel, behind
the glove compartment.
It evaluates the signals from the outer door handle
sensors and then activates the antennae for access
and start authorisation.
The capacity-based operating sensors in the outer
door handle detect any contact on the handle and
send a signal shortly afterwards to the antenna
read-in unit for keyless access authorisation.
The antenna read-in unit evaluates the signal and
then sends a query to the vehicle key via the
antennae for access and start authorisation.
The sensors switch off after approx. 80 hours once
the vehicle is locked or after 20 actuations without
an authorised key.

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)
