Navman iCN320

Cheapest on test by a quid, this Navman felt rugged and well made, while the solid bracket held it firm. Entry via the keypad was simple, and we liked the split-screen display which showed pictograms of the next two manoeuvres. It doesn't provide a constant view of vehicle movement or show anything if no route is planned, but it vies with the i3 for cheapest and best occasional use device.
