Navman iCN520

The interface on this Navman is superb, as it takes hardly any getting used to and offers many of the right options. There's a touch-screen, complete with a stylus, which worked better than the fiddly manual rotary button. It's quick to route, re-route and find satellites, and we also loved the display toggle switch, which enabled four views to be swapped at will. But the lack of a full postcode search and a high price meant this Navman slipped to third in our budget standings
