What is a calibrate compass on a Pontiac Bonneville?

A calibrated compass on a Pontiac Bonneville is a feature typically integrated into the vehicle's navigation or information system that helps determine the car's directional orientation. Calibration involves adjusting the compass to account for magnetic interference from the vehicle's metal components and electronic devices, ensuring accurate readings. This process usually requires the driver to drive the vehicle in a specific pattern or follow on-screen instructions to align the compass correctly. A properly calibrated compass enhances navigation and helps drivers maintain their intended course.
