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 MIO A701 is a jack of all trades device designed to replace your mobile phone, GPS unit and PDA. Sporting a touch screen but no keypad, the versatile A701 also boasts a 1.3 megapixel camera and both MP3 and video players.

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.

The E51 has some questionable design choices, which have dragged down the overall quality of the product, but it's a sturdy phone with all the features a business user could possibly need.

If you want a fully fledged GPS navigator, you are best off purchasing either a portable in-car unit or a handheld device with a larger screen. If you want to track your fitness data, then the HGE-100 may be worth a look.

We were expecting big things from the 6210 Navigator, but the fact that turn-by-turn navigation is only free for six months is a huge disappointment. We can’t see the point of this handset when most handsets in Nokia’s new range offer GPS and Nokia Maps.
