Electronic compass, purpose

n

The electronic compass (B26) determines the current route
of the

vehicle using the
earth's magnetic field
and passes the appropriate

data to the trip computer control module (N41) via a two-wire

interface (RS485).
The compass has a calibration mode to allow the route to be

determined as accurately as possible. In this mode the compass can

be adapted to the magnetic conditions around the vehicle.
