I live in HK and got the Fenix 5S Plus ROW with the US maps, as I didn't want an APAC device. I loaded the local HK & China maps from OpenStreetMap, which works fine for navigation. But when I try to calibrate barometer/altimeter using DEM it tells me that no DEM data is available.
I assume this data is bundled with Garmin's Topo Active region maps? If so, any other way to get DEM data?
