Updating the Software Using the Garmin Connect App
Before you can update your watch software using the Garmin Connect™ app, you must have a Garmin Connect account, and you must pair the watch with a compatible phone (Setting Up the Watch).
When new software is available, the Garmin Connect app automatically sends the update to your watch. The update is applied when you are not actively using the watch. When the update is complete, your watch restarts.
