Now the changed navit.xml is working. But it is crashing now while loading the maps binfile. I have downloaded maps from 'http://maps.navit-project.org/' for OH state in U.S. But when I looked into the maps in the above site at the highest zoom level, I am not seeing any roads or city/street names. Is this the site I should download maps from?? They are mentioned as opensteet maps - precompiled, ready to use.
