Compass: Description and Operation

This mode displays an 8 point compass heading on the left hand side of the DIC. The compass will display the current vehicle direction relative to one of 8 compass headings using N,NE,E,SE,S,SW,W, and NW for the readout. The compass display is updated once every 2 seconds. The DIC will always display the compass reading and outside temperature. On Buick vehicles with automatic HVAC (RPO CJ2) the DIC will not display temperature, the ambient temperature will only be found on the HVAC control head display.

When the compass requires calibration, C or CALIBRATE COMPASS displays. For compass calibration and compass magnetic variation adjustment refer to Electronic Compass Calibration.
