Hi all

works with open source maps.
Evenso there are no flying maps availabe yet (have to check, if you can create your own maps), its a nice little program for the new mobile phones with inbuild or via bluetooth coupled GPS.
Different to most GPS-programs for mobiles, it works totally offline, that is without downloading maps (you have to have them on your phone)
So when abroard you won´t be surprised by the bill from your provider.
Nice back-up, when installed on you phone ;-)
