With the extra street navigation software, this is extremely versitile. For example you can set parameters such as allowing or not allowing U turns, so if a road is blocked and you turn around, you force it to find an alternative route. I also use it on a sailboat, and like the "velocity made good" feature. Recently I took it on a cross-country air flight, and could tell the speed of the plane, its elevation, the elevation to which the cabin was pressured, and also what I was looking at out the window, and where I was, etc. I held it to the window to help it locate itself, and then could just set it on the tray or the tray of the seat one over from the window.
My first GPS was a Garmin 12. This is both much easier to use and enormously more capable. I went for a color unit because it is easier to read outdoors. |
