I don't know why you guys are confusing him. Poland shows up just fine on the City Navigator maps. Wolsztyn is visible and available down to the same street level that every other place in Europe is. I'm looking at it now. (The zoom level in Garmin Mobile PC is 30 meters altitude; the map in the Garmin link above only zooms to 100 meters.)
Smokeyone, if you get GMPC in Europe, it will have Garmin City Navigator Europe maps as the default maps. (Don't be confused by the name; they cover all of Europe, not just cities) I have plotted a number of routes in Poland, and the program was invaluable in helping me out. I'm sure it will do the same for you.
