Your other option could be to purchase a Navionics Update card for $99. use your old card to activate it. The old card can still be used with what data is on it, you won't be able get Daily Updates, but the Navionics Update card will have free Daily Updates for one year.
https://youtu.be/JBMDA-Eabr0I wrote to Navionics and got much the same advice about getting an update card. I did not know that this would prevent the old card from getting updates, though. If I got a new Lowrance unit with Lakemaster map, and used that as the "sacrificial" chip, would that allow me to still update the original Navionics as well as the Update chip?
