Gps mobile phones

TomTom and Garmin SatNavs are flying off the shelves, and it’s no surprise; GPS (Global Positioning System) lets you know exactly where you are the in the world down to around 10m, including altitude and even which direction you're pointing. Originally designed for the US military, the civilian version can now be found everywhere from cars to your mobile phone. All of these GPS mobile phones have built-in GPS, turning your phone into a powerful SatNav for anything from route planning to finding your nearest cash point or curry house!
