Calibrating the compass

If an Empower module or the optional accessory battery pack is installed or removed from the device, the compass must be re-calibrated, or you may experience poor accuracy.

A device that is exhibiting poor accuracy may have bad calibration data on the device. In most cases, this will be resolved after performing one to four calibrations to clear out bad data and correctly calibrate the device. If the compass still appears inaccurate, more calibrations may improve this.

If the blue dot's beam is wide or pointing in the wrong direction, calibrate the compass:

  1. On the device, open the Google Maps app.

  2. Make a figure 8 until your compass is calibrated. You should only have to do this a few times.

    The beam should become narrow and point in the right direction.

For more information on improving your device accuracy, including the instructions on how to perform a calibration, refer to the Google Maps Help page.
