Thanks for the help! I am trying to export my shapefile into GPX, and when I run the tool, it says my points have no geometry. I had added a Lat and Long field and populated with 'Calculate Geometry' in decimal degree, and my map and layers projection are WGS 1984. I'm not sure how to address this issues. I know I have some projection issue because I tried going around the tool by saving my feature as a shapefile in a folder and pulling into DNRGarmin and saving as GPX in there, and my points were not in South Florida as they should be, but were in Montana.
Because Pro is clever enough to reproject on-the-fly it can be hard to know when your layer is in a different projection to the map. I'd go back and double-check the projection of the shapefile, make sure it is the correct projection (if none then 'Define Projection' GP tool), then reproject into WGS84. Then export to GPX.
