Thanks for the comments and advice
- much appreciated. I will follow-up with C-Map if I can contact them. It seems that they have split from Jeppeson and have not yet sorted out their phone
lines. Reaching them by phone
has not been possible. They ignore email
contact via their online "contact us" mechanism on the C-Map website.
I recently purchased a C-Map card for the South Pacific
and I have asked the dealer that sold
it to me the same question as I posted on this site. Sadly, they don't know but plan to ask C-Map. I'll ask the dealer to ask C-Map about a compatibility plan for OpenCPN.
