I've came over to garmin after buying a 645M, after time using polar beat and flow with my phone and H10 chest HRM. One of the very best features of those apps are being able to click on the zoomable route map view and pull a slider along and it moves a dot along the route while giving distance/time/pace/HR at that exact spot. It's really ideal for analysing a session and it doesn't seem like anything proprietary, are there any plans for garmin to introduce something like this into connect?
