Latest edition Sat-Nav's are far better than paper maps, for the cost of an atlas that is updated once a year I get as many updates as I want during the year so always know when road layouts have changed, speed camera's added, etc.
Plus the added bonus of live updates on the move for roadworks and accident's means I may drive a few more miles but I dont end up stuck in traffic jam's for hours on end wondering what is happening and wasting precious fuel.
With the better makes of Sat-Nav you can also change the voice with a free download from the net. I keep swapping who is giving me the directions so it dosn't become boring or annoying.
Plus once set you do not have to touch the Sat-Nav again during your journey, with a map you have to make frequent stops to check where you are going as it is illegal to use an atlas while driving because you are not in full control of the vehicle.
