My Axiom came with an 8 GB card for the Navionics charts. 8 GB is somewhat small for the sonar map charting that is available from Navionics. What is the largest card I can use in the Axiom 12? Can I use a 32GB card? It would hold a lot more Navionics sonar data and wouldn't require constant updating for long trips.
