From Halfords’ own-brand range of sat-nav devices, the Navsure 300i is a curiously chubby little fellow.

It’s also the only system in our group to run on four AA batteries rather than a rechargeable power cell. Heavy and oddly shaped, the Navsure is a little awkward to carry when it’s not docked in the car.

At just 2.7 inches, the Navsure also has the smallest screen of all the units on test, which makes it both more difficult to see and harder to be accurate when tapping on the touch-sensitive screen.

The navigation software worked pretty well, albeit slightly slowly. Its great failing is that it doesn’t accept full UK postcodes, which means a lot of extra tapping on that little screen. It’s not perfect by a long chalk but, at only £120, the Navsure 300i is undeniably good value.

This article is part of a group test of satellite-navigation devices.
