My guess is that there is a problem with your software map database that came with the unit... doesn't sounds like that there is the "city navigator-NT 2010" installed, some where in the system setup menu in the unit there must be a item called "MAPS", there you find a list that will tell you what kind of maps are on the chip and which are active or deactivated.
In case you got the "city navigator-NT 2010" on the chip which I don't think you have, look if you got the maps from Turkey, Greece, all the Baltic and most of the Balkan without Serbia and the Ukraine....
I agree bad spelling in a map address/database is not a trusty start off...
