The 6120 Classic may not be outstanding, but it is stylish, affordable and has a generous features list.

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 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 N95 packs in just about every feature under the sun. Most are welcome additions, but there are a few issues that prevent this from being a great smart phone.

The StreetPilot c510 is a solid budget offering, and has a few features that are usually reserved for more expensive models.

It's amazing that Dopod has managed to fit so many features into such a compact smartphone. You need to pay extra for mapping software, so the P800W is far from a cheap investment, but for some, the all-in-one convenience makes it worthwhile.

The nuvi 250W is a solid unit and the widescreen display is certainly a nice touch for an entry-level model, but its missing a few features to warrant its price tag.

The nuvi 250 is a solid unit and commands a lower price than the 250W, despite possessing the same features.

The nuvi 660 adds a larger display and Bluetooth hands-free calling to an already solid previous unit, but some small deficiencies still remain. Best of all though, the pricing difference between models is minimal, so the 660 is definitely worth the extra money.

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 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.
