Compass Calibration When on,the compass automatically calibrates asthe vehicle is driven. If, after two seconds, display does the not show a compass heading (N for North, for example), there may be a strong magnetic field interferingwith the compass. Such interference may be causedby a magnetic antennamount, magnetic note pad holder or a similar magnetic item. I the letter C should ever appear f in the compass window, the compass may need calibration.
