As far as i know they both pick up the 30's and 40's...not sure if the 320 gets the old 20's.  And I'm 90% sure you can NOT get birdseye on the 220, even though you can get some decent topo maps.  I think the 220 you need a map card and the 320 you can just plug into the comp to get the topo, but dont hold me to that
