No, just Navit. Navit uses the vector maps, while Maemo Mapper uses raster maps.

Navit works, but is extremely non-user friendly.

Hotz, use the Navit wiki. It really helped me. http://wiki.navit-project.org/index.php/Main_Page

I use emelfm2, then find the file (make sure you can see hidden files), then use the find function to find Openstreet, then enable the mapset, change the path to where my map is, and disable the demo map.

I hope that helped.
