I had just purchased the HRM-Run (old model) to monitor running dynamics and running power with my Forerunner 645. This strap came with SW 6.30 which doesn't have the newest running dynamics capability (GCT balance, vertical ratio, stride length). I understand that with other Garmin models, updating with the HRM-Run connected led to downloading a SW update (to 6.60). Prior posts mentioned that this is seen on Garmin Connect under the devices/accessories & sensors section. On the current Garmin Connect I don't see a sensors section and I am slowly going bonkers trying to figure out how to update the software, if it is even possible at this time. Garmin users and Garmin, please help!
