Hi, I have a Raymarine A98 with a Navionics Platinium Plus, For the past 12 months the SonarChart Live has been working great, re-maping with 0.5M contours at 100M +, My 1st 12 months subscription has expired, I can still see/use my old re-maps, but cannot create new. Navionics Australia tell me I need a new card and will lose my re-map data, I understand that I can update subscription on line, and will not lose my data, Has anyone done this successfully, if can you please advise how
