Try reading a map in a large strange city, on a bike, trying to find your destination. No thanks. It is so easy to type in your destination in 20 seconds and then drive right to it via the shortest route. I remember when I got my first GPS unit for my job, and Instead of looking at maps, it saved me several hours of time each week. Any of you who have not tried a gps or dont have one are missing the boat. For the cheap cost, they are one of the most easiest, safest gadgets to use, and handiest thing you can travel with. And the large digital speedo that is available on them by just hitting one button is invaluble. No looking down at the speedometer, which takes your eyes off the road. I have mine on all the time just running around town for the speedo. So much safer... Maps???? No thanks...huge waste of time except to plan your trip. Gas stations?...I can check on the GPS while getting gas how many miles it is to the next town gas station and compare that to my miles left in the tank reading. That has been a life saver also.
