At DEMOfall 2006 - DASH Navigation: Very cool navigation product.

DASH connects to the web using a wifi or a cellular network. It is feature rich. The coolest feature is that multiple DASH devices collaborate to generate the traffic profile of an area. The information is then used to generate the best set of directions based on traffic flow. This clearly beats the "shortest distance" algorithm used by the current navigation systems.

Other features include the mash-up of other information (restaurants, gas stations, etc.) drawn from the internet with the maps. They also have a way to display gas prices with the gas stations. This is clearly the future direction for all GPS devices.

DASH is backed by Kleiner and Sequoia.
