I went out and hook up unit first time on my boat. Two questions, how do I get the vessel in GPS to point direction I am headed. Also when I turned the unit on, it had me near Punta Rasa and an X. When I move to where I have the boat, it showed the vessel. How will it show my location, will it show when I start moving. Also when I want to go to waypoint, should I just pick the waypoint and direct it to Go to? thanks for any help
