I have the Sd card installed and when I go into the Garmin Express it says I have no more maps to install. I have found that the unit will accept the GPS coordinates and works out the route perfectly it just won't allow me to change the country to Germany or Italy, they're are not listed. I am a bit wary about deleting the maps in case I can't reinstall them. I am going to Germany on Thursday so I think I will just use the coordinate method and maybe look further into it when I get back.
