Ive been seeing more and more of them on the tube and wondered if anyone here has or used one and how they are programmed as far as individual maps and directions. I see that there are several companies making them with different graphics and tho what little ive seen of them they are pretty expensive tho I can see how one could be very handy, especially if it is easy to see while driving and in real time as far as your current location, direction, etc. and would beat having to stop every so often and be looking over the atlas. I was also wondering if they have a function like a GPS where you can save different locations to memory.
