I got this GPS with high hopes, I travel a lot and I am tired of printing out tripquest maps. I hooked it to my computer and downloaded the latest updates. Everything about the unit works great, it is easy to use, I love how it talks to you, easy directions, etc. However, at least in my area, the maps are wrong, worse than an online free map service. Just in town it was wrong three times in one day and on trips around this area of a 150 miles or so it was wrong each time. Maybe it works well in larger more urban areas but it isn't ready for primetime here yet. I returned the unit and of course Amazon's customer service was great as always. I'm hoping maps for these improve in the future as they continue to come down in price. I am very disappointed but I can't justify the price for something that is wrong so often. The bottom line is the map needs to be correct most of the time.
