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.

Despite being an entry level unit and commanding a very reasonable price tag, the Navigator 3000 falls short in a few areas.

The C320 is very similar to the successful C520, minus a couple of features. It represents great value for money at this price point and is ideal for first time users, or those who just want a GPS unit without extra bells and whistles like Bluetooth and multimedia functions.

The XL adds a larger display to the already fantastic ONE unit. The new EasyPort mount and TomTom’s Map Share feature make this an enticing unit.

Navigon’s 2150max is certainly reasonable value at this price. Lane assistance, text-to-speech and Bluetooth hands-free combined with comprehensive safety warnings and a reasonably intuitive interface make it a credible choice.

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.

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.

The ONE has received a facelift and although the improvements are largely focused around the aesthetics, this is still one of the best value for money GPS units on the market.
