A good GPS receiver, but the irritating audio notifications and lack of advanced customisation features mean this isn't the device to take on long drives.

There's no denying the convenience of having a combined PDA and GPS unit, but we have seen easier to use GPS units.

If you're on the lookout for a smaller and simple to use GPS, the Streetpilot i3 would be ideal. More advanced users will be frustrated by the limited control set and slow calculation speeds.

While Tom Tom does get credit for trying with the Rider, there are some key flaws with this GPS solution that have to be overcome.

A solid option that is fairly well priced considering the features offered. The iCN530 is a good choice, but keep in mind that some of the newer Navman models offer refreshing interface changes and newer map views.

The MMP-401 is basically the MMP-501 in a smaller package and without the Bluetooth hands-free connectivity. It does a reasonable job for quite a good price.

The Navigator 7000 is outstanding for road safety thanks to its "Road Sense" subscription, but its navigational performance could be improved.

The 330 Auto Navigation is Nokia's first stand-alone GPS. The result is a solid, but not outstanding unit that is let down by an impractical address search method.

Although the GPSmap 60 is functional on at least a basic level, it has a black-and-white display and a relatively high price point. With no expandable memory, slow acquisition times and a confusing control scheme, there’s no reason not to spend a little more and buy the Colorado 300.
