I loaded CN V9 onto my 2610 before we did Baltics and found it worked fine, V9 only has full detail for capital citys in the baltics and the base map was fine on the open road
Poland is now fully mapped the only problems we had with the Gps were due to me not reading the user's manual before we left
If you look on Garmin site its shows you what countrys have full mapping ...
I'm into oldschool still, no money for a GPS, a way too overpriced per their purpose, creating too much hassle, expensive thing to be broken or get stolen... and a big detailed map is still vastly more advanced and detailed than a 2 inch screen. You see guys with 3 GPSes on board asking for directions
Anyways Regio has a CD for GPSes too, I've got one collecting dust. Dunno what compatability (Garmin, Magellan etc) it has. I'll try to check it if I'm back home.
