Newcomer to electronics, so please pardon if this is a dumb question...my dad got a Garmin 73sv for his boat. I have the Navionics app on my phone and have lots of waypoints marked in my app. Is there a way to transfer them to his Garmin? I know it uses Navionics maps but I haven't figured out a way to transfer the waypoints yet. It would sure be nice to show up at the lake and pull up on his Garmin the points that I marked while doing my homework at home.
