My old Garmin HR strap bit the dust, and I remembered that I also have a Polar HR7 bluetooth strap. When I try to connect it the 520, it never finds the HR7. My phone can connect to the HR7 using the Polar Beat app. That tells me that either the 520 can't see the HR7 by design or due to something going wrong. Which one is it?
Thanks for helping out.
