"I purchased this GPS system from another entity and I must say, it is a great buy. The best features of this product are the lighting features when driving at night - there is no glare against the windshield. I use this more than I thought I would and actually depend very heavily on it. My first big trip was driving from CT to Pittsburgh, PA - no issues at all and never lost the satelite contact even when driving in remote areas. Other great features are the automatic rerouting feature. If you make a wrong turn, it automatically adjusts itself saving you the frustration of getting back on track.
The one drawback that I find (and I've had this product for over a year now) is that sometimes, it has a hard time finding satelite contact. When you're in familiar territory, it's no big deal but if you are traveling, it can get frustrating. This is the reason for four stars - otherwise, it's a great tool especially if you are traveling and need to find a place to eat or a hospital. I wouldn't be without it."
