If all is set and the times match, then what you will get will be little picture icons-- along your rouute that match the time based on camera and the time that is equal to it on on your GPS. No need to set any waypoints, just track and go. so at 1:21:03 seconds you took a pic then at 1:21:03 on your gps it will show the pic icon at that moment.. Pretty cool feature.. Hope that helps
