Our course and a growing number of courses use EZLocator for the superintendent staff to use in order to plan out their daily pin placements and provide that data to members. Today they provide printed out pin sheets as well as an app that you can download onto an Apple phone. EZLocator also have integration with Club Car golf carts where you can see the pin location on the GPS screen on the cart that shows not only front/middle/back but also the distance to today's pin.
Request would be for Garmin to integrate with that data and expose it onto the relevant current and future watches/devices for both live play as well as post round data analysis for approach stats, putting distances, etc. Seems like the data is there and you should be able to consume it. Right now you need to eyeball it and move the flag along the green display prior to stepping on the putting surface and that is ripe for improvement.
