I use a Garmin Map60C. Its a hand held that you can buy a dashmount and DC powercord for, its in color and always draws a line behind you on the map so you can always turn around and follow the line. I also have a handle bar mount for it thats on my mountain bike, or you could do the same on an ATV. Its in color and the newer version has an SD slot to hold enormous maps with the use of a big SD card. Very good for the money!
