All Garmin wearable models that sync over Bluetooth Smart, with the Garmin Connect Mobile app running on a mobile device, will upload the activity record to the cloud-based Garmin Connect service automatically, if the mobile device is connected to the Internet over the cellular mobile network, or over Wi-Fi to a Internet-connected gateway or router, at the moment the user completed and successfully saved a run on a watch that is connected in turn to the GCM app.
