I was going over a recording i made this weekend with humviewer when i came across an object that i want too investagate next time i go out.I set a waypoint on the object i seen the waypoint on humviewer but when i put the SD card back in my unit the waypoint was nowhere to be found.So my question is if you make a waypoint using humviewer how do you get that waypoint in your unit so you can navigate to it when your on the water?
