Therefore designs sat nav for Tom Tom

London product design consultancy Therefore has designed an in-car satellite navigation system for travel products group Tom Tom, called the Tom Tom Go. Encompassing a 3.5-inch touch-screen 3D display with illuminated maps and a stereo voice-guidance system, the product uses Global Positioning System technology to pinpoint the driver’s location. Users punch in their destination to the device, which sits on the car dashboard, and it plots the route. Tom Tom Go is powered by a rechargeable battery that lasts up to five hours.
