Summary: I am not sure if the seller was aware of this so I am not judging; however the GPS I received from him was factory repaired and it included software to run the unit that was many years ancient; and the mapping software including functions were way out of date. I bought this GPS specifically to take on my TN wilderness fishing trip with a buddy along with a local guide in order to mark way points of the local "hot spots" so we could return in a few days and limit out.
Summary: I bought this unit rather than a Garmin because of it's ability to use Nat'l Geographic high resolution Topo maps. However, it has confusing screens and the manual is virtually worthless. It tells you what is obvious, but little else. The compass feature is especially frustrating. There is little about the unit that is intuitive. The screen I. D. isn't very informative, leaving you to drill down the wrong path, often. I'd consider alternatives.
