Compass Calibration

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

Before calibrating the compass, drive the vehicle to an area that is magnetically clean or free of large metallic objects. Verify there are no magnetized objects on the inside or outside of the vehicle close to the mirror.

  1. Start the engine.
  2. Press and hold the switch for the compass, which may be depicted as COMP, COMPASS, or On/Off (w/UE1) depending on the type of mirror on the vehicle, until the letter "C" or "CAL" is displayed.
  3. Drive the vehicle in circles at a speed of less than 8 km/h (5 mph) until the "C" or "CAL" is replaced by a proper vehicle heading. The calibration procedure is now complete.
