JadedTraveler - my experience with the US version of the nuvi 350 with the additional European map data card was like the previous poster in that I did encounter a single miscounted exit except one just north of Shannon where the roundabout had a new exit added for entry into the new section of a motorway. That section was opened the week I was there and an updated map would not have shown it. We were also able to find all the restaurants and pubs we were looking for thaat were recommended by locals.
