Another neat feature is the 7100's subscription-free live traffic service. Although not as robust as competing paid services, it worked well on my tests, automatically muting me around traffic incidents. The 7100 also has a trademarked Reality View that gives you a photo realistic depiction of upcoming complex intersections- a big help when you're driving in unfamiliar territory.

Otherwise, the 7100 is pretty typical, featuring a 4.3-inch widescreen WQVGA display, a SiRFstarIII GPS receiver, and Navteq maps. The device supports car, bicycle, and pedestrian speed profiles, as well as multi-segment routing. It generated fast and accurate routes, and its text-to-speech engine did a good job of converting street names to voice prompts. The 7100 also recognizes voice commands for saved destinations.

If you’re traveling to one of the cities that are covered, the Zagat guides are a nice feature to have. With some small improvements in POI handling and the Bluetooth interface, the Navigon 7100 could be a real winner.
