This works as well as I can test. I compiled it with gpsd support but since I don't have a USB gps I can't confirm that it works. It complains that it can't find one, so at least I know it is trying. Maps can be created on your desktop with the standard Navit maptool or whatever. The build comes with a default map of Munich just so you can see what's going on. To add your own maps, create a "maps" directory in the "pandora/appdata/navit" directory on your SD card and drop the created bin and XML files in there. http://repo.openpandora.org/?page=detail&app=navit If anyone can actually get a GPS unit working that'd be awesome.
