Garmain 492

[Badsanta]

I have a new in box Garmain 492 chart plotter I am going to use. Garmain has software updates I can download to my PC. I then transfer to a data card and then transfer that to the 492.
But garmain no longer has that data card.
Anybody have an idea what I need and where can I get one?
Many thanks in advavce.
