Although the S150 doesn't have all of the features of its more expensive sibling, Bluetooth hands-free remains, as does the excellent navigational experience.

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.

The R600 is a solid, but not outstanding GPS unit. Its large display and simple user interface are positives, but the large, bulky size, combined with a lack of text-to-speech technology are downsides.

The iCN 320 is a low cost GPS unit equipped with a basic features set and designed for use straight out of the box. This will appeal to new buyers who are put off by the high price of in car navigation, but those wanting more advanced options would be advised to look elsewhere.

The S102 comes at a good price, but although the navigational experience was solid, it just doesn't do enough to command a glowing rapport. There are plenty of better options available on the market.

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

The AVIC-S2 is well equipped and despite a somewhat confusing map experience, it remains a recommended, if not outstanding purchase.

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 top-of-the-line Moov 370 features a clean look and feel thanks to its redesigned map and menu interface. The absence of split-screen technology is a disappointment, as is its speed, but traffic updates, safety alerts and Bluetooth help sweeten the deal.

TomTom’s latest addition to the navigation market continues the company’s fine form when it comes to the user experience. The GO 730 adds some excellent software features to a package that we’ve come to know and love.

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.
