Linux based Navigation System

Dash Express Navigation System shares both hardware and software components from Neo FreeRunner mobile phone which is first mobile uses linux as a platform.

The Dash Express is positioned as the first in-car navigation system to feature a continuous connection to the Internet. The Dash network monitors available wireless options and chooses the best pick between cellular radio and Wi-Fi 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. 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. 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 manufacturer.
