Permanent location finding
Is the calculation of the current vehicle position.
It is active when the ignition is switched on and is performed by the navigation processor radio and navigation integrated into the 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
