The ONE 3rd Edition adds an excellent safety feature to an already outstanding unit, though it's a shame battery life hasn't been improved. Regardless, it's definitely great value at this price.

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.

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.

The S30 is an ideal GPS unit for those on a budget. The entry level unit combines a stylish design with good maps, a reasonable feature set and a very competitive price.

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 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.

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

The C220 is a solid choice if you're after an entry-level GPS unit. Excellent maps, speedy performance and a competitive price may be enough to overlook the sometimes confusing interface.

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

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 F40 is a mid-range unit, with an excellent user interface and clear maps. The included hands-free module only sweetens the deal.

The ONE XL adds a larger display and a new design to an already outstanding GPS unit. At this price, it's the best value for money on the market and combines excellent navigation and an outstanding user experience.
