Updating the HRM 600 Software

The HRM 600 can receive a software update from a connected Garmin® device, or directly from either the Garmin Connect™ app or the Garmin Express™ desktop application (Connecting the Device to Your Computer).

  1. On the HRM 600 module, press the button to wake it up.
  2. Bring the devices within 3 m (10 ft.).
  3. Select an option:
    • Sync your compatible Garmin device with the Garmin Connect app.

      If an update is available, the connected device will prompt you to apply the update for your HRM 600 after your next activity.

    • Sync your HRM 600 with the Garmin Connect app.

The HRM 600 LED flashes Orange and Green while updating. When the update is complete, the HRM 600 turns on and the LED flashes Green 20 times. If the update fails, the LED flashes Red 20 times.
