How to factory reset your Garmin Forerunner 305


The reason I have a need for this is because in recent runs the Garmin has been reporting the correct time yet when I upload to Garmin Connect the time is often inexplicably a few minutes more. I am hoping that a factory reset of the watch will resolve this.

Important! Please note that this will erase all personalised settings and any previous training data. Back up any data before resetting.

– Power off
– Hold down both the ‘Mode’ button and the ‘Power’ button
– When the watch powers on select ‘Yes’ to ‘Do you really want to erase all the user data?’
– The watch automatically restarts and prompts to select location, time zone and other Garmin specific accessory settings
