Continuous positioning finding means that the current position of the vehicle is calculated. It is active when the ignition is switched on and is carried out by the navigation processor (N41/1).During the switch-on phase (software is loaded), only the basic position finding is available. After switching the ignition off, all important positioning parameters are stored for the duration of the run-on time (approx. 30 min). Once the run-on time has ended, the COMAND operating, display and control unit (A40/3) switches itself off completely.

After the last navigation step (destination reached), the position map is displayed once again on the display of the COMAND operating, display and control unit (A40/3).

Constant location finding uses 3 methods which supplement each other mutually and thus guarantee very accurate and reliable location finding. These include:

• Basic position finding (dead reckoning)
• GPS position finding
• Map-supported map matching

Manual entry of vehicle location 

It is possible to enter the vehicle position manually in the "navigation" menu of the COMAND operating, display and control unit (A40/3)
