This is a very good product. The only downfall is that you must update the cd prior to roaming out of the areas you have already loaded. Sometimes, due to new road construction, it routes you off but the most fantastic part of this is that if you make the wrong turn, it recalculated and instantly locates where you are and finds another option. I use this all the time in my business travels, and it has saved me time from being lost. One point to remember, if your travelling inside large cities, the garmin doesn't know the difference between good areas of town, which are not always the safest routes. Be aware and lock your doors!
