by the navigation processor Integrated Into the radio and navigation module (A2/56) .

During the switch-on phase (software is loaded), only basic map matching is available.

When the ignition is switched off all important location finding parameters are stored for the duration of the
shut-off delay (approx. 60 min) .

The permanent location finding feature uses three procedures which supplement each other ensuring very
precise and reliable location finding:



Basic location finding (dead reckoning)



Map-supported location finding (map matching)



GPS location finding

Manual entry of vehicle location

It is possible to enter the location manually on the operating and display module. This can be useful in the
following cases:



Following vehicle transport

(e.g. ferry or train) or



when GPS reception is not present when trip is started

Function

The data for navigation voice output is stored originally on the navigation DVD. They are transmitted with the
help of the DVD drive of the radio (A2) into the memory of the navigation processor and are then available
anytime for navigation.

The language is reloaded in the following cases:



automatically, after voltage to the radio (A2) was interrupted



manually, by activating the "SPRA" menu in the navigation mode

Loading the language requires approx. 20 s.

If the system is switched off while loading the language, the language data is lost and must be reloaded again.
Avoid strong vibrations to the vehicle (e.g. extremely bumpy roads) while the language is being loaded.

The navigation processor is integrated in the radio (A2).

BASIC LOCATION FINDING, FUNCTION - GF82.61-P-3006D

MODELS 163, 168, 170, 203.0 /2 /7, 208, 209.3 /4, 210 with CODE (353) Audio 30 APS

Basic representation of the basic location finding shown on model 210

Basic location finding (dead reckoning) is the basic function of continuous location finding. It is permanently
carried out by the navigation processor that is integrated in the radio (A2) when the ignition is switched on
(approx. once per second) and is irrespective of the data of the DVD map. After switching off the ignition, the
current position is stored for the duration of the system shut-off delay time.

Fig. 46: Identifying Basic Location Finding Function

The following information is calculated with the aid of basic location finding:



Distance traveled



Absolute vehicle direction (compass direction)



Direction of travel (forward or reverse)

Calculation of distance traveled

The navigation processor receives the wheel speed signal of the following components:
