How big of a map can you put on a 320?

[cuyama87]

I have a 32gig card in my 320 but I can only put a like 1.67gigs o map on my gps

What I am asking is can you put more on? It only lets me put around 180 sq miles I think

Put the map directly on your card then insert it. Sounds like its saving the map to internal memory

I had the same issue, but like tman said, put it right onto the card. You can do that from basecamp also, just make sure that it is dropped on the card, and not onto the gps.
