birds eye

im thinking off downloading birdsseye to my 320 will that effect my map card or over write the card. or will they wor together.. and how much does the bird eye few will it show the whole state of nc or just what i download

They work together and it will only show what you download. If you get in an area where you don't have downloaded it will switch back to the topo map. I have seen it a few times but didn't care much for it. I can tell more about the topo map but that's just me.
