confusion..

I downloaded the app and installed it but i dont have maps, i dont have a data plan so i cant goto the internet through my phone and download them.. im confused on how i can get maps from the net and put them on my phone through my computer.. is that even possible?/ i checked out that website but i just dont understand really what to do? can someone point me in the right direction?

serial proxy

maps can be downloaded over bluetooth. use the utility serial proxy and you cann connect navigami to the internet using your pc.
