Summary: Most of what these reviews say about the unit is mostly true. But I was still disappointed with the unit's overall performance. To be fair, I think the biggest problem I had was how outdated the maps were. My first trip was from my home to my office (to try it out). My office building was constructed about 3 years ago. The road and the building are not on the unit's map. So the directions were not optimal. Later, I took a trip to the NC mountains.
