Electronic GadgetYou have seen in-dash navigation for your car but how about this nifty gadget. Navigation built right into your steering wheel. This devices will give the driver information such as open doors and low tire pressure and also works with "the Navigon 7100. The 2-way system can communicate with the Navigation System and relay important information straight to the 12 o'clock position on the steering wheel. Also, by using the sensors already on board, the Navigon can more accurately gauge speed, direction and the attitude of the vehicle." The steering wheel is manufactured by Takara and is not going to be released OEM at this time.
