On the Garmin Edge, you can see the Gear Ratios of your bike if you have a Di2 D-fly in your system. It will be cool to have the gear ratios displayed on my metrics overlay for my cycling race footage!
This would be cool but I doubt it's going to happen as cameras do not pair with Di2. You would have to import the data from the edge (which I know is possible but I doubt they will support this).
I would love that too, this is probably very easy to add, we just should use an activity from a compatible device until eventually adding pairing di2 with the camera.
Plenty of data the Edge tracks, not the camera and it comes over to the video seamlessly. This is just another data point. I would request they add eTap as well.
