Magellan’s Maestro 4250 provides an alternative to the more expensive, high-end TomTom and Garmin devices. Although it doesn’t provide the same level of polish as some of the better known brands, its features are functional and it provides everyday users with a viable GPS option.

Costing the same as a low-end automotive GPS unit, the Triton 200 forgoes a touch screen as well as turn-by-turn and voice navigation in order to specialise in detailed mapping for outdoor activities. However, without the expandable memory required for detailed maps, the Triton 200 doesn’t provide the functionality necessary for more complex hiking and geocaching adventures.

The Moov 360 is a similar unit to its big brother, but without traffic capabilities. If you are hell-bent on traffic updates, then go for the 370. If not, then there is plenty to like about this unit.

The compact size of this unit doesn't compensate for its poor GPS performance. Not recommended.

As an entry-level unit the Moov 300 is a solid GPS device and an ideal choice if you happen to be on a budget. It may lack the bells and whistles of its more expensive counterparts, but it nonetheless provides a reasonable navigational experience.

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.

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 massive improvement over earlier MIO models, the C510 includes good maps, clear voice instructions and added features like Bluetooth hands free.

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.

Without a doubt the best GPS unit Mio has ever released, the C520's delightful widescreen display, split-screen technology and text-to-speech navigation makes this one of the best units we've reviewed.

The C310 is an entry level model that is reasonably well priced for what it offers. First time users may take a while to grasp the bells and whistles of navigation, but otherwise, this is a solid unit.
