In an effort to give its product the edge, the Navman N40i’s manufacturer has integrated a 1.3-megapixel camera into the unit.

It’s not the most obvious of features for a GPS device and the idea that you’ll take pictures of locations and store them for navigational reasons is a pretty flimsy one, although you can access locations visited by others on the Navman website and download the navigation details.

You’re unlikely to want to ditch an existing camera for the N40i either, since image quality is poor.

It’s just as well, then, that the rest of the package is fairly strong. Detailed maps for Europe are included on CD, for example, and the 3.5in screen is bright and sharp.

In our tests we experienced some occasional hangs when tapping onscreen buttons, but generally the device was pretty fast and maintained a strong link to the satellite signal.

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