Syncing Activities and Performance Measurements

You can sync activities and performance measurements from other Garmin® devices to your D2™ Air X15 watch using your Garmin Connect™ account. This allows your watch to more accurately reflect your training and fitness. For example, you can record a ride with an Edge® bike computer, and view your activity details and recovery time on your D2 Air X15 watch.

Sync your D2 Air X15 watch and other Garmin devices to your Garmin Connect account.
TIP: You can set a primary training device and primary wearable in the Garmin Connect app (Unified Training Status).

Recent activities and performance measurements from your other Garmin devices appear on your D2 Air X15 watch.
