This device is perfect for anyone. Lets just say anyone who can't get this to work should give it to their teenager to set up for them. Easy set up and great Google Earth inforamtion. I own a Executive Limousine service and this is the best, knowing how drivers are driving and where they went with the vehicle (Makes them not cheat on time slips when they know I know whats going on). If you cant figure how to use this then I suggest you go back to school and learn how to read past the 5 grade to understand how easy this is to operate.
