Compass Variance
Compass Variance is the difference between Magnetic North and Geographic North. To compensate for the differences, the variance should be set for the zone where the vehicle is driven, per the zone map. Once properly set, the compass will automatically compensate for the differences and provide the most accurate compass heading.
NOTE:
• A good calibration requires a level surface and an environment free from large
metallic objects such as buildings, bridges, underground cables, railroad tracks,
etc.
• Magnetic materials should be kept away from the top of the center of the instrument panel. This is where the compass sensor is located.
