I understand that your sensor wirelessly connects with the Garmin GPS units (I have a Garmin Forerunner 310xt and may upgrade to the 910XT) as does their heart monitors. But while I can set up the display on the 310XT unit to show my HR in real time (as well as many other data fields), how would I set up the display on the 310XT to show the cadence information that the Vaaka is sending? Is the cadence info only available post workout when I download the workout session to my computer, or can I see the cadence (stroke rate) on the screen in real time?

Also if I upgrade to the Garmin 910XT will the Vaaka need to be upgraded as well (from one that paired with the 310XT model)?
