Did you mean "cp /media/mmc1/maps/navit.xml /home/user/.navit/navit.xml"
"cp /media/mmc1/maps/navitOSD.xml /home/user/.navit/navitOSD.xml"
I still can't get it working, can't even get it to display a map, let alone routing. Will the navit.xml need the map binary name adding? (I added UK only as europe is over a gig)
