Numerous people have told us they are having the same problem with their GPS device (all different brands) in Canada and Alaska. The routing seems fine but the GPS says "make a u-turn, then an immediate left) putting you back on the correct route. Not sure why but we just ignore it and we never depend on just the GPS. We always have printed directions too. You do have to input Lat/long coordinates up here because many places just do not have traditional addresses. We have only missed one turn while on this trip and that was in Grand Prairie, Alberta because the GPS went crazy. Grand Prairie also had the worst frost heaves we have encountered and were not marked.
