Well,
I;ve had my Fenix 3 since they 1st come out, and have been very disappointed in the Garmin Connect Website.
The main issues, and I am comparing them to Suunto's Moves Count site (which I had a Ambit 2 before hand, and still transfer my Garmin moves over too)
1) Full screen map, seriously how hard is this to implement. It's probably the most important feature but you are stuck to a small letter box sized screen, which is useless
2) Your Courses route, why you cannot add in the ability to add way points / POI's. Instead we have to go to 3rd part sites / apps (Ride with GPS, Route Planner) etc to add in waypoints, to get turn notifications.... This is just poor form.
3) The scale of the altitude in the graphs. The graph has a way to make everything look flat, the scale should be dynamic. If I go for a run and it's between 0 and 100 metres above see level, why would I want to see the graph go to 200 metres,
4) Dynamic graphs. Suunto Moves Count site does this very well. I click on altitude, and it will colour co-ordinate the corse path to that of different colours according to the altitude. Click on Heart Rate, it will then change the colours to that of the different heart rate levels, very handy to see what your heart rate / altitude (and any other metric) is at a certain point.
5) Any apps I put onto my Fenix 3, are not graphed out, or uploaded. Completely useless as when your activity is done, any added in metrics are not saved on the watch or in the web site.
There are a few other issues, bit the above are really getting to me. I'm awaiting the next generation of Ambit Peak as currently Suunto's website can do all of the above.
I'm just hoping they will allow editing of POI's / waypoints on the watch, and also change other settings (this is what is good on the F3) and nice to have bread crumb tracks as well....
Anyway rant over, as I've seen all the above requested many times, and still nothing is done.
