There are a few instances in which a master reset may want to be performed on the Edge 305 or 205, such as:

  • Not functioning properly
  • Needing to be restored to factory default settings
  • Not receiving a satellite signal*
  • To bring up language selection prompt if incorrect language text is showing
  • Unable to pair up accessories, such as the heart rate monitor or speed/cadence sensor (305 only)

All settings, workouts, courses, and satellite data may be erased when resetting the GPS. Workouts can be backed up to such training programs like Garmin Connect.

To perform the Master Reset:

  1. Power device OFF
  2. Press and hold Mode and Power
  3. Release on buttons once the Do You Really Want To Erase All User Data? message appears
  4. Select Yes

The Edge 305 or 205 is now reset. Leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.

*If the device is not receiving a satellite signal, perform an AutoLocate before performing a master reset.

If the device will not power off, try a soft reset.
