I am trying to get a mirrorlink compatible app to work with my head unit and stumbled on MapTrip. It uses OpenStreetMaps data for navigation and I'd like to install maps to the phone. The problem is it appears to convert the maps to some other format, so here's where I need some help. Map download is Germany only, in the .geo format. I would like to download maps for North America. Does anyone know a way to convert OSM maps .osm to .geo format?
There are other xml files as well that point to .att, .iln, and .iqt files.
