The Speed Sensor can be updated by compatible Garmin head units (e.g. Edge 1030, Forerunner 935, fenix5).
- Garmin head units will automatically detect when there is new software, and prompt you to update your sensor.
The Speed Sensor can be also updated via the Garmin Connect Mobile app.
- Go to the sensor device page (More → Garmin Devices → select sensor)
- Under General Settings, the software version and any available software updates are displayed.
