Can I connect Edge 540 Solar and Polar Vantage V2 watch? I've used the watch for a few years and it's the only sport watch I've ever owned so I'd like to stick with Polar Flow and the data it has gathered over the years. I got 540 Solar for a great price from local outlet and I bought it mainly for navigating. If the two devices can't be connected, am I missing some great features if I used the Edge without HR? And would HRM Dual or Polar H10 help me with this?
