The TomTom GO 500 adds handsfree capabilities to an already impressive set of GP features.

While we have seen other GPS units equipped with basic safety warnings, the Road Sense sofware on the RoadAngel Navigator is by far the most extensive and practical implementation of safety features we have seen on a GPS to date.

The iCN 720 is a solid GPS unit that works well and includes a digital camera, navigation using photos, 4-inch touch screen, remote control and easy to navigate interface.

A larger screen enhances an already enticing package. The N60i is an excellent GPS, with a great user interface and quality maps.

If you can live without a slide out QWERTY keyboard, the D810 is an excellent option for those after a HSDPA smart phone. Sleek, stylish yet still packed with features, it comes highly recommended, although price is steep.

The gogo CM310 is a very solid navigation device, even though its multimedia features aren't outstanding. But a fast, distinctive interface, an included 1GB SD card and USB card reader and the presence of turning "blinkers" differentiate the CM310 from the crowd.

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 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.

For those that don't need 3G or the Pocket Office applications you get with a Windows Mobile 6.0 device then the BlackBerry 8820 is a clear and highly desirable choice.

The S50 adds Bluetooth handsfree and NavPix for a reasonable price. Although there is no camera to take NavPix photos, it's still a useful application.

The S80 is the third product in Navman's S-Series range and introduces text-to-speech technology to an otherwise largely similar unit to the S50.

For those who like the idea of practically carrying a mini-notebook in their pocket, the E90 Communicator is one of the most comprehensive available. It won't appeal to everyone but despite the lack of TV-out and fax features, it is the best of business phones.
