Query: Excellent product but....

Have used the GPS continually on a 100 day cross Canada, cross East Coast of US trip. The rating is mostly sensational. Got us into and out of tiny towns and backwoods and in and out of New York City. Clear concise directions. Problems are twofold. Had us exiting near Philadelphia on the right when the exit was actually on the left - 6 lanes away. Secondly in driving along East Coast on brand new freeways it thought we were driving through open fields of hay. Since I just bought it this past August - I felt the maps should have been more up to date already. Otherwise I love it!!!!!!!!!!
