I lost my heart rate monitor and bought what I believe was the exact same one that came with the 620 although now that I look at it the box does not say 620 on it. I think still the product was just released in a box prior to the 620. It does look exactly the same. Since equipping my new one with the FR620 I can get Cadence but I can't get any of the other run dynamics even with them enabled on my watch.
What is up with this?
:confused:
