You only have to look at the absence of Bluetooth and WiFi support to see that the n35 is a navigation device first and a handheld second.

The GARMIN StreetPilot is a reliable and easy-to-use GPS unit.

This tiny handheld GPS receiver includes maps, intelligent routing algorithms, an intuitive display, and can be programmed with custom data sources or integrated into enterprise applications. Quest is a good alternative to more complex location-aware platforms.

The nuvi 660 adds a larger display and Bluetooth hands-free calling to an already solid previous unit, but some small deficiencies still remain. Best of all though, the pricing difference between models is minimal, so the 660 is definitely worth the extra money.

If you can overlook the size and the rather basic entertainment features, this GPS does the job and for what it offers, the MMP-501 comes in at a very respectable price point compared with many other units on the market.

While not as visually appealing or easy to use as other GPS unit we have reviewed, the GPS on the 169 did its job. The PDA however, lacks Bluetooth and Wi-Fi support.

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.

A larger screen enhances an already enticing package. The N60i is an excellent GPS, with a great user interface and quality maps.

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

A solid and portable GPS navigator.

The AVIC-F500BT is a unique but welcome addition to the navigational market. This is the perfect device if you want to add the latest in navigation and entertainment to your vehicle without altering your existing stereo.

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