card that came with my Raymarine
chart plotter stopped working. I paid for and was wanting to download new charts
from the Navionics
website, but I'm now told by Navionics that they require one of their own working cards, as they're write/encryption protected. I'm sailing though Mexico
(currently in a small town), am on the move constantly, and have no mailing address. Their only "authorized dealer" is over 1,000 miles away. Does anyone know a way to get the Navionics download app and my plotter recognize a regular card? Is there some file that needs to be on it?
