[DG] [DG11] Which microSD card for Axiom 7?

[DIYglenn]

Hi!

I'm about to purchase C-Map 4D Max+ for a Axiom 7.
Now I'm wondering what microSD-card should be used for the map?

The retailer said they only have 1GB cards, which for me sounds like a very small amount.

As the Axiom only has one slot, wouldn't it be best to go with 32GB or even larger? They're so cheap today, so why limit to 1GB.

Does it matter? Can the Axiom actually store anything at all on the microSD, or is it only the map?

I thought maps were delivered from C-Map / Navionics ready to use, not having to be set up by the retailer...
