Best car tech: Dash Express

Our winner in the car tech category was Dash Navigation's Dash Express, which takes GPS navigation to the next level. With its two-way connectivity--giving it access to other Dash units--as well as its preprogrammed, historic traffic-flow data, Dash Express has the potential to provide drivers with real real-time traffic information. Its Yahoo Local search gives drivers access to a points-of-interest database as big as the Web itself, and Dash throws in neat features such as the ability to search for gas stations by fuel price and for movie theaters by showtime.
