The Dash Express is more than just another automotive navigation system: it’s a peer-to-per network with social components that can use cellular and Wi-Fi networks for communication.

The idea behind the Dash is that it’s smarter than the average navigation and traffic reporting system that receives updates just from one source. Instead, each Dash collects details from other Dash units used by other drivers on what the company calls the Dash Driver Network. The unit shows three potential routes based on actual traffic flow, updating those en route.

While local search isn’t unique to the Dash Express, its ability to use GPRS (slow cell data) or Wi-Fi means that you’re likely to get better performance in fixed places when you’ve stopped to pull up information if a Wi-Fi network is nearby that you can access. The system emphasizes Yahoo Local, but works with other search engines.

Each Dash Express has an email address that allows you and others to send address information directly to the device, eliminating docking and other necessities. Local information “lists” can be shared among Dash users via a Web site that manages the contents of custom information on your Dash.
