4. Navman iCN 750
The interface on this isn't great, but the NavPix software and 1.3-megapixel camera are noteworthy features. Essentially, this allows you to take a picture of a location and, as long as you have a GPS fix at the time, the unit will record the site's coordinates. Then you can save the photo as a favorite or point of interest, and use it to quickly get directions the next time you want to visit the location. In-car GPS devices are evolving, but this is one of the more innovative features we've come across.
Editors' rating: 7.0
The good: The Navman iCN 750 has a 1.3-megapixel camera that lets you create photo-based points of interest and comes preloaded with maps of North America.
The bad: The Navman iCN 750 is a bit sluggish to perform tasks and its interface isn't always intuitive. The screen is also hard to see in bright sunlight.
The bottom line: Though a bit sluggish, the Navman iCN 750 is an innovative image-based navigation system, offering an integrated camera and accurate driving directions.
