GPSMap60c is inexpensive, wow when did that happen? 20 hours is great especially when you are always next to a SuperAmerica. Like I stated, if you are in a major city getting a good map and learning to read it - is the most cost effective way. Besides, I have 4 portable GPS units can not think of anytime they have worked well in my car - inlcuing my. I am glad others have found them to work well.
