This almost does what I want it too. I bought this as a replacement for a GPS V - a very good GPS mapping system in its own right. I require a larger memory capacity, and a larger screen, so I got it here. The color screen is much easier to read. The 128 MB card and USB programmer are wonderful, and provide me with a set of maps for nearly all of my trips without having to hook up the unit to the computer for an hour or more for a half day's worth of maps.It has a couple of flaws, the mount isn't perfect, so if the car vibrates, then the GPS does too. The GPS V, didn't have this problem, it was rock solid. Nor can I alter the fields that are displayed in map navigation mode - the GPS V would allow me to change the fields, so I had miles to go until the destination - now I have to switch to the directions page for that.
