The Forerunner and Edge from time to time may not lock onto satellites. This can be due to corrupted satellite information. Performing an AutoLocate will clear previous GPS data and allow the device to lock onto its current position.

You may also need to perform an AutoLocate in the following circumstances:

  • The device has not been used in over two weeks
  • The device is powered on in a location that is 50 or more miles from where it is normally used
  • The distance or speed data appears to be inaccurate as a result of a corrupt satellite signal

The AutoLocate instructions listed below pertain to the following fitness devices:

  • Forerunner 910XT, 310XT, 305, 205, 301, 201 or 101
  • Edge 305 and 205

To perform an AutoLocate:

  1. Ensure device is powered off
  2. Press and hold Down button
  3. Press and release Power button
  4. Wait 30 seconds
  5. Release Down

After the AutoLocate is performed on the device, allow 15 to 20 minutes to acquire the current position with a clear view of the sky. The fitness device should now function properly.

If acquisition issue persists, it may be necessary to update the device software or perform a reset (Forerunner - Edge).
