Off hand, I know probably three addresses: my current home, my childhood home, and work — obviously, I don't need GPS to get to any of those places. Visiting Mt. Rushmore is a different story. I know what it looks like and the state it's in, but without directions, I'd probably find myself lost, roasting away in the middle of the Badlands. Navman has an interesting solution to this problem. The Navman ICN750 GPS unit, scheduled for a European release in May, can access a database of searchable images to help locate your destination. If you want to visit a site like Rushmore, just find a picture of the monument on your Navman, click, and directions will pop up. Sounds great for recognizable landmarks, but how is it going to help find Aunt Anne's house in rural Vermont? It's got a solution: the 750 has a built-in camera and 4 GB of memory. You can snap a photo of a destination and your Navman with store the location. Of course, that doesn't help much the first visit, but for subsequent trips, just find her picture and off you go. The ICN750 is priced at $937. — Trevor Noren
