I would know if is possible to use other maps in the free version of the app, like ".map" extension. I would know too is is possible use TomTom maps at the free version? If is possible, how I could make it? My other question is about the ".kmz" extension. I created a route in the Google Earth and then I exported the route to kmz extension. The Navigator Free is able to read this extension or I would need to convert this file too? To all this cases, at what directory I should put them?
