You might want to also check out a couple of other projects

• Mapper - a "friendly fork" of maemo-mapper (http://mapper.tal.org) that features a predefined list of maps, a few less features, but lots more stability.
• Navit - uses vector data and allows routing on the fly without a network connection. It's still rough (not even alpha level). (http://wiki.navit-project.org/index....t_on_n770/n800)
