I'm onto my second Gear Fit2 Pro, and both haven't displayed a map. I tried all the tricks such as ensuring active bluetooth & internet connnections.
However, I'm using the Fit2 Pro with an iPhone.
From reading this thread, I gather the maps don't work for Fit2 Pro devices paired to iOS. The maps only seem to work for Fit2 Pro devices pair to Samsung/Android.
Of interest, the Gear Fit2 Pro uses Here WeGo maps rather than Google (when working that is).
