The gogo CM310 is a very solid navigation device, even though its multimedia features aren't outstanding. But a fast, distinctive interface, an included 1GB SD card and USB card reader and the presence of turning "blinkers" differentiate the CM310 from the crowd.

A large, bulky unit, the MMP-501B offers a great display and plenty of features for its asking price, though there aren't many new additions from the previous model.

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.

The upgraded MMP-401B offers text-to-speech technology, an improved user interface and red light, fixed speed camera and school zone warnings. At this price, it's good value.

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 FD-250 has most of the basics and a few extra features that will serve you well, but the lack of responsiveness of the touch screen is an issue.

Laser’s Navig8r M35 is one of the best value for money GPS units we've come across. Don’t let its low price fool you: it is packed with features, including detailed mapping data and Australian-accented text-to-speech.

The LN800 offers a larger screen and a light sensor, but we don't think its worth the extra asking price over the LN800. Still, it's a solid unit with a fair list of included features.

At this price, the LN500 is an excellent choice, especially for a first time user. Text-to-speech technology, solid Destinator software and a stylish, slim design are enough to put this near the top of your list if you are on a budget

Magellan's CrossoverGPS unit is a fair effort, but it's lacking in some areas. If you do your fair share of walking and boating though, this is definitely worth a look.

The Triton 400 provides the perfect companion for travelling and hiking. It doesn’t offer the luxuries of Magellan’s more expensive models, but it provides the necessities for successful travel at a fairly reasonable cost.

It may have a hefty price tag but the Triton 2000 offers plenty of features. The touch screen makes this device much easier to use than units that only have a navigational pad.
