Can someone help me, I have a navionics sd chart it works fine in my Lowrance chart plotter , but I have just noticed a little switch on the side of the card and wonder what it’s for. They came with the boat and I have no instructions for it. And maybe I can impose further on your knowledge , I am now getting a message no gps signal , and on looking on the internet it would seem that my gps module is busted , there are a few that look suitable on eBay would anyone have any idea as which would be suitable for me , thanks.
