Navigation device uses Linux phone platform

Updated 3:40 P.M., PST] -- A Sunnyvale, Calif.-based start-up announced a WiFi- and GPRS/GSM-equipped navigation device based on a newly upgraded Linux-based mobile phone platform. Dash Navigation's "Dash Express" borrows both hardware and software components from OpenMoko's forthcoming Neo FreeRunner mobile phone, and boasts continual two-way Internet communications.

The Dash Express is positioned as the first in-car navigation device to feature a continuous connection to the Internet. The Dash network monitors available wireless options and chooses the best pick between cellular radio and WiFi to download traffic data, map updates, and other information from the Internet. The always-connected architecture enables an interesting "user-influenced" traffic monitoring system, in which Dash computers anonymously transmit location information to the Dash network, which can advise drivers of best routes, the company says.

The Dash Express is based on the Neo FreeRunner design (pictured at right) that OpenMoko unveiled yesterday. The FreeRunner updates OpenMoko's original Neo1973 -- one of the very first Linux-based phones to feature a user-replaceable OS -- with a faster processor, new 3D graphics acceleration, WiFi, 850MHz triband GSM capability, and 3D accelerometers.

Dash Express uses the Neo FreeRunner's hardware design minus the 3D graphics acceleration, accelerometers, and Bluetooth, and adds 3GB of flash storage (instead of 256MB), as well as a stronger GPS receiver and larger antenna. The navigation device also borrows the open source Linux kernel and bootloader maintained by OpenMoko.org, a community effort to build a mobile phone entirely from open source software. However, despite its close relation to OpenMoko, the Dash Express is not designed to run user-modified Linux stacks.

CTO Bob Curry explained, "We can upgrade the OS over-the-air, but unlike the Neo phone, the Dash Express is not designed for hacking."

Both the Dash Express and the Neo FreeRunner will be manufactured by OpenMoko's former parent company, First International Computer (FIC) -- one of the world's largest consumer electronics and PC manufacturers -- and both will be demonstrated by OpenMoko at next week's CES (Consumer Electronics Show) in Las Vegas.

Touted Dash Express features include:
Two-way Internet access via WiFi or cellular communication

Navigation and mapping features

Unlimited Yahoo! local search

Traffic routing system combines data from traditional traffic sources with anonymously gathered traffic information from other Dash-connected drivers

Routing service provides up to three options to each requested destination based on flow patterns rather than incident data

Service is claimed capable of automatically alerting drivers when a faster route becomes available
