Hi,
so now I've got the DE Topo Map (http://www.navitotal.com/forums/showthread.php?1802-TOPO-Germany-2010-MapSource-version-unlocked&p=6275#post6275), unpacked it and installed MapSource from the given URL. Everything worked fine so far, but I just won't get the maps into MapSource or on my device. MapSource lists the map name in some unlock dialogue, but there's nothing I can do. How does it all work?
