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.

What is claimed is: 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. 2. The system of claim 1, wherein the wireless communication protocol is a Bluetooth protocol. 3. The system of claim 2, wherein the network protocol is a Controller Area Network protocol. 4. The system of claim 3, wherein the gateway node is a Controller Area Network/Bluetooth gateway node. 5. The system of claim 1, further comprising a memory, wherein the processor saves the current position in the memory, the current position becoming the former position when the processor retrieves the current position from the memory. 6. The system of claim 1, wherein the at least one sensor is at least one of a wheel speed sensor, a velocity sensor, a yaw rate sensor, a steering angle sensor, a body-slip angle sensor, an attitude sensor, and an inertial sensor. 7. The system of claim 1, wherein the processor is situated in a hand-held computer. 8. A device for navigating a vehicle comprising: a processor, the processor configured to receive at least one datum wirelessly from a gateway node using a wireless communication protocol, the at least one datum corresponding to at least one of an instantaneous sensor value and a time-averaged sensor value; and a positioning device 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. 9. The device of claim 8, wherein: the wireless communication protocol is a Bluetooth protocol; and the gateway node is a Controller Area Network/Bluetooth gateway node. 10. The device of claim 8, wherein the positioning device communicates the initial position to the processor. 11. The device of claim 8, further comprising a memory, wherein the processor saves the current position in the memory, the current position becoming the former position when the processor retrieves the current position from the memory. 12. The device of claim 8, wherein the processor is situated in a hand-held computer. 13. The device of claim 12, wherein the processor and the positioning device are integrated in one unit. 14. The device of claim 12, wherein the positioning device is at least one of a GPS receiver, a DGPS receiver, an AGPS receiver, and a cell-phone-based positioning system. 15. The device of claim 14, wherein the processor determines the current position in an area of at least one of low-coverage and no-coverage of at least one of a cellphone-based positioning system and a satellite navigation system. 16. A method for navigating a vehicle comprising: measuring at least one datum by at least one sensor, the at least one datum being at least one of an instantaneous value and a time-averaged value; transmitting electronically the at least one datum from the at least one sensor to a gateway node via a vehicle bus using a network protocol; transmitting wirelessly the at least one datum from the gateway node to a processor using a wireless communication protocol; receiving an initial position from a positioning device at the processor; and calculating a current position by the processor using at least one of a former position, the initial position, and the at least one datum. 17. The method of claim 16, further comprising communicating an initial position from the positioning device to the processor. 18. The method of claim 16, further comprising saving by the processor the current position in a memory, the current position becoming the former position when the processor retrieves the current position from the memory. 19. The method of claim 16, further comprising determining, by the processor, the current position in an area of at least one of low-coverage and no-coverage of at least one of a cellphone-based positioning system and a satellite navigation system.
