Ford Mustang (2005-2014) Owners Manual: Electronic compass

The compass heading displays in the center-integrated display.

Note: Driving near large buildings, bridges, power lines and powerful broadcast antenna may affect the compass reading. Magnetic or metallic objects placed in, on or near your vehicle may also affect compass accuracy.

Usually, when something affects the compass readings, the compass corrects itself after a few days of operating your vehicle in normal conditions. If the compass still appears to be inaccurate, a manual calibration may be necessary. See Compass calibration adjustment.

Compass Zone Adjustment

When something affects the compass readings, typically the compass corrects itself after a few days of operating your vehicle in normal conditions. If the compass still appears to be inaccurate, a manual calibration may be necessary.

1. Determine which magnetic zone you are in for your geographic location by referring to the zone map.
2. Turn ignition to the on position.
3. Press and hold the 7 and 9 radio preset buttons together for approximately five seconds until ZONE XX appears.
4. Press and release the 7 and 9 radio preset buttons together, repeatedly until ZONE XX changes to the correct zone (1–15).
5. The direction displays, and the zone updates, when you release the buttons.

Compass Calibration Adjustment

Most geographic areas (zones) have a magnetic north compass point that varies slightly from the northerly direction on maps. This variation is four degrees between adjacent zones and becomes noticeable as your vehicle crosses multiple zones. A correct zone setting eliminates this error.

Perform compass calibration in an open area free from steel structures and high voltage lines. For optimum calibration, turn off all electrical accessories (such as the heater, air conditioning or wipers) and make sure no vehicle doors are open.

1. Start your vehicle.
2. Press and hold the 7 and 9 radio preset buttons together for approximately 10 seconds until CAL appears. Release the buttons.
3. Drive your vehicle in a circle slowly (under than 3 mph [5 km/h]); it may take up to five circles to complete calibration.
4. Calibration is complete when the CAL display changes to the direction value (such as N, S, E or W).
