I am looking for a new maps program fore the N900 that has offline map downloading (not just caching but proper "download everything for this area over this high-speed DSL link and only download new stuff if its changed" ala Nokia Maps) without needing to manually input specific coordinates/sizes for the map (I want it to know what "Australia" or "Brisbane" is and download it for me, just like Nokia Maps does). Google Transit GTFS data set support would be awesome (i.e. being able to display bus stops etc on the map and see all the services going from those stops and when) as would a nice sane address/location/poi search. Don't need turn-by-turn or voice navigation since I dont drive a car

Does such a maps program for the N900 exist?
