1. A system for navigating a vehicle comprising:
- at least one sensor situated in the vehicle, the at least one sensor configured to sense at least one datum corresponding to at least one of an instantaneous sensor value and a time-averaged sensor value, the at least one sensor electrically coupled to a vehicle bus;
a gateway node situated in the vehicle, the gateway node electrically coupled to the vehicle bus, the at least one sensor configured to communicate the at least one datum to the gateway node via the vehicle bus using a network protocol;
a processor, the gateway node configured to communicate the at least one datum to the processor using a wireless communication protocol; and
a positioning device, the positioning device electrically coupled to the processor, the processor adapted to use at least one of a former position, an initial position, and the at least one datum to determine a current position.

Abstract
A method and system for a wireless interface to the electronics of an automotive vehicle for a remote application in the vehicle or within communication range of the vehicle. The remote application may be a navigation system using vehicle motion sensor data to provide or improve a navigation solution for the vehicle. In an alternative embodiment, the remote application is diagnostic software running on a handheld computer that evaluates vehicle systems in a diagnostics procedure.
