You have to have an internet connection to get routes in Maemo Mapper. If you do have a connection, then the usual reason for having problems freezing when trying to get maps and routes is a bad card. The internal card seems to be reset to read-only with some frequency, and I've quit using it, downloading everything to the external card. I've had no problems with that, after many using the internal card. Nokia doesn't seem to have all the bugs worked out of the internal card slot/driver.
