Can I copy my Navionics card?

So I have the Navionics North SD card I believe. I use it for navigation in my Helix 10 at the wheel. I also have a Helix 7 at the front but it only takes a micro SD card.
Has anyone tried to copy the SD card onto a micro SD? Is it protected somehow to not allow this? Maybe download to PC and transfer onto the micro SD?
Sure would be nice to be able to use the navionics card in my Helix 7 since I use it as my hardwater unit.
Probably a dumb question but seems like this could be done unless there are copyrighted reasons? Not like that ever stopped people anyway.

No. The format the sd card needs can only be done by navionics.

Doesn’t matter if it’s Lakemaster, Navionics, Lowrance, whatever. If you could copy it, you could sell copies to everyone you know. They have to copy protect the cards or they wouldn’t be in business long.

Copying a proprietary SD card is a copyright infringement and against the law. But, if you have a card that is no longer published and no longer available from the original publisher, you might try one of the sector by sector copy programs available on the internet. Some of them are available for free.

I have never done this, but it is worth a try.
