Well… it looks like the X2 and my Garmin Edge 520 do not want to play nice in the garden. Before I choose the X2, I asked if it would work with Garmin… “Yes” is what I got. But there is a qualifier: BLE only, no ANT+, so no communication with the 520; too bad because I do a lot of cycling. Now, are there any plans to to enable ANT+ on the X2 through firmware or hardware updates? I need to correlate the data from my cycling workouts to my heart data on a realtime display.
