4-channel power amplifier for vehicle loudspeakers
System interlinkage
The radio and navigation unit (A2/56) is provided with the following components for data exchange with
external digital components:
CAN (A1 -A2/56)
The radio and navigation unit (A2/56) is connected with the instrument cluster (A1) via a separate
CAN bus. The difference to the other CAN systems is indicated by the spelling CAN bus (A1-A2/56).
The CAN bus (A1-A2/56) allows the following functions:
Operation of the radio and navigation unit (A2/56)is also possible with the multifunction steering
wheel.
The multifunction display (A1/p13) in the instrument cluster (A1) can display navigation
information on the current operating status of the radio and navigation unit (A2/56) .
The connection to the CAN bus (A1-A2/56) is only realized on models 208 and 210. (Status 3/99)
Digital data bus (D2B)
Data can be exchanged between the external audio components, the telephone system and - if present -
the voice control system over the D2B bus. This allows control data as well as the actual audio signals
(e.g. music from CD changer) to be transferred.
The only additional D2B component presently possible is the CD changer (A2/6) (Status: 3/99)
K bus (diagnostic interface)
Data exchange is accomplished between the diagnostic interface and the hand-held tester (reading out
DTCs and actual values, ...).
The communication between the HHT and all other D2B components is accomplished over the radio
and navigation unit (A2/56) diagnostic interface.

The evaluation of the wheel speed signals reveals the mileage covered.
The wheel speed signals of the not driven wheels are evaluated, since their slip between the roadway and tire
is lower, which results in a more accurate result when calculating the mileage.
Calculation of the vehicle orientation
The navigation computer calculates the direction in which the vehicle is traveling (compass direction) from the
data from the gyrosensor and the sequence of locations calculated with the aid of the global positioning system
(GPS). The difference in the calculated mileage and the mileage actually covered between 2 turn-off points is
used to automatically recalibrate the tire circumference (necessary due to tire wear).
Calculation of the direction of motion
The navigation processor recognizes the direction of motion (forward or reverse) from the reverse signal.
Calibration of tire circumference
As a matter of principle, the navigation system recalibrates itself while driving as described. However, this may
require driving a longer distance. After changing tires, manual recalibration should therefore be accomplished.
To do this, it is necessary to enter the tire size (e.g.:195/050/015)and possibly the following information:
new tires (tread depth > approx. 5 mm)
used tires (tread depth < approx. 5 mm)
The entry can be done two different ways:
With aid of STAR DIAGNOSIS.
By calling the "Navigation --> TIRE" menu at the radio (A2)
Errors due to vehicle movement with switched off ignition lead to an inaccurate basic location finding.
Rolling backwards without the reverse gear engaged is evaluated as forwards motion, and may lead to an error
in the location finding. Rolling with the ignition switched off or vehicle transportation also falsify map
matching.
The errors are, however, corrected automatically after a short time by the navigation processor after
receiving GPS data.
A special calibration drive by driving around a defined test path is not ever required.
