I understand that the Speed Sensor 2 has an odometer integrated with the sensor (ie records all mileage by the sensor regardless of whether a device (edge, watch, etc) is connected or a workout is undertaken. But...how can these data be viewed? I have connected the sensor to a Forerunner and the Garmin Connect app on phone, but neither of these appear to allow you to view the odometer data - is this (only?) possible with an Edge device? Pretty frustrating if so!
