Just starting to dig for the impossible. Has anyone been able to create their own Navionics
cards to use in Raymarine
c and e series MFD?
Of course the current
crop of carteridges are encrypted and breaking the encryption is out of the question legally and difficult technilogically.
Was there an earlier version of their charting format that was not encrypted? Does anyone know the data layout for the cards? Has this been done?
I'm thinking that it would be nice to make your own cards with selected charts
from public sources. Hard to do of course.... but not impossible.
