A semiconductor device has a semiconductor substrate having a peripheral circuit area and a memory cell area. The apparatus further includes a magnetic rotor assembly rotatably coupled to the housing. When establishing communication between the base station and the moving station, if the current vehicle position generally matches any driving route created and stored in the storage unit earlier, automatic driving control is performed with the matching driving route serving as a target driving route. The phone then transmits the audio signals to the vehicle media system for playback using an unlicensed wireless technology.
