That does help. However, my problem really is the time it takes to make changes in OSM. In general in my area (Ohio, USA) most of the highway/road crossings are currently treated as intersections which is incorrect. There are a large number of these in the area and would take quite some time to correct. Additionally, in at least two cases that I have found (and I am sure there are more) roads seem to be made up of multiple segments, making navigation impossible. One is a residential street, the other is Highway 80 a major toll-road that cuts across Ohio. On the whole, a monstrous task that I simply don't have time for, it would take going grid by grid, checking each street and intersection, making corrections where needed and moving to the next area.

I haven't been able to get any Garmin maps (I've tried multiple maps) for my area to work either. It appears to load (no errors in xterm), but nothing shows up on the screen when that is the only map enabled.

As such, although I love the idea of Navit, its' use is very limited for me in my area, it might get me by in a pinch, but I couldn't trust the maps outside of an area that I am semi-familiar with.
