Any advice on how exactly to up date a ES 97 from light house II to Light house III? I tried to several times but I am obviously doing something wrong. I received the email from raymarine with the upgrade. put the file on the card and inserted it but I must be missing a step.
The file size was about 240k.
Any advice would be appreciated.
Thank you,
