	Electronic compass location	The electronic compass, also known as the compass module, is mounted on a bracket, which is clipped into the combination bracket frame.
	Electronic compass task	The electronic compass is used to measure the direction of the near-earth magnetic field and thus determines the heading direction of travel. Only 8 typical cardinal points (N, NW, W, SW, S, SO, O, NO) are shown in the multifunction display (A1p13).
	Electronic compass design	Magnetic field sensor for measuring alignment of near-earth magnetic field EPROM memory for continual storage of given calibration data and settings
	Electronic compass function	Transmission of direction information as from active CAN-B Compensation of spurious magnetic fields such as, e.g. heated seat DIAGNOSABLE Performance of self-test, when ignition switched on
