I have a
Raymarine 435i with no
charts in it. Manual says
Navionics gold card. Some places say no 1XG, 2XG. I got a card that is a "XL3
Classic or Gold" 1G905XL3. In the plotter it comes up "No chart files available". In a card reader on my computer, the files show up. I tried opening them with
Open CPN and SeaClear and can't do that or don't know how. Anyone got any ideas?
