Navman iCN 330 Portable GPSWhether it's A to B, or even A to Z, finding your way should be easy. Which is why we made the iCN 330 as easy to use as reciting your ABCs. When we designed the iCN 330, we didn't want a sat-nav device that only rocket scientists could use. So we made it as simple to use as possible. There are also lots of ways to plan your route, so you can be on the move quickly and easily. Once en route, the iCN 330 displays your route on a 3D moving map, in 2D or instruction-by-instruction. What's more, whenever a maneuver is coming up, the progress bar turns red. And if, despite our best efforts, you do miss a turn, the iCN 330 automatically recalculates a new route with its Back-on-Track function.
