Compass Heading Is Blank

Excessive magnetism in or near the vehicle may cause the compass display to go blank. In order to distinguish between vehicle magnetics and surrounding magnetics, drive the vehicle to an area that is free from large metal objects. Rest the compass by cycling the ignition (OFF and ON). If the compass display goes blank within 20 seconds after the reset of power, then the vehicle magnetism is too high and the vehicle should be degaussed.
