Displaying Route, Function

Function requirements:
Ignition: ON
Tailgate closed

Displaying the route
The compass function can be selected by pressing the Mode button (right-hand button, N41s2) on the trip computer (N41). The direction in which the vehicle is facing then appears on the display of the trip computer control module (N41).
The route is displayed as a point of the compass N, NE, E, SE, S, SW, W, or NW. The display shown is valid for Germany. If other countries are selected, the display changes according to the language of the particular country.
The directions are always displayed as the first letter of the points of the compass (e.g. North, South, East, and West).

Accuracy
The display is accurate to 10°.
The accuracy can be affected by nearby magnetic influences (e.g. tall buildings, bridges, power cables, transmission units, magnetic or ferromagnetic objects).
It is important to set the correct compass zone to ensure the greatest possible accuracy. The compass must also be calibrated

Networking
The trip computer control module (N41) receives information about the route from the electronic compass (B26) via a serial two-wire interface (R6485).
The status of the tailgate rotary tumbler microswitch (S68/1)), which is read in by the all activity module (N10) ,is sent to the trip computer control module (N41) on the engine compartment CAN.
