Summary: Researched this gps unit before buying. Tech reviews online were very favorable. Have used the unit a couple of times and it works well. Have yet to test it on a long trip with multiple destinations. I have no reason to doubt it's ability and accuracy. A great buy for the features it has.
Excerpt: I bought this GPS before a trip to the Southwest having never used one before. It was extremely useful and worked well, with clear directions getting us to the right places. It's also useful for pulling up a map of the area. My only problem was that it wasn't clear how to delete or go backwards.
