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.

Magellan's CrossoverGPS unit is a fair effort, but it's lacking in some areas. If you do your fair share of walking and boating though, this is definitely worth a look.

It may have a hefty price tag but the Triton 2000 offers plenty of features. The touch screen makes this device much easier to use than units that only have a navigational pad.

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.

A solid easy to use GPS unit. The iCN 550 has an easy to use interface and comes pre-loaded with Australia, Europe and North America maps.
