Navsure N400i

For less than £400, the N400i is one of the cheapest ways to get an integrated sat-nav in your motor. The head unit is controlled from the pop-out seven-inch touchscreen, and it has preloaded maps. Directions are relayed via the vehicle’s speakers, it can play CD/MP3/WMA files and has an RDS AM/FM radio. If only Christmas always worked so seamlessly!
