I am thinking of purchasing the "Heart Rate Monitor" https://buy.garmin.com/shop/shop.do?pID=10996 for my Dakota 20.
Looking on the GPS I have worked out how to change a display item on the "Trip Computer" page to be "Heart Rate".
I am however wondering if the heart rate data will be available on Garmin Connect i.e. will it just be imported automatically, and show perhaps in a similar way as with the elevation data? Also will an average heart rate / average moving heart rate be available?
