Navit doesn't use osm files directly but it converts them to it's own
binary vector format.

TangoGPS uses the prerenderd png files from the osm website and i don't
know if it is possible to pre-cache them except for doing it within
tangoGPS itself. The Problem with the png files is that they are
downloaded for every zoom level because they can't be resized like the
vector format. :/

The pro of the png format is that it can display any kind of map data
(sattelite, topo, etc) while the vector format can't. But the vector
format is much smaller and can be zoomed to any level.
It would be nice if tangoGPS could use vector format for osm and png
format for the other repositories. But i think this would need too much
rework of the rendering engine. ;)
