[0020] The conditions for normal operation of the TV on some existing vehicle navigation multimedia information display units are that the gearshift position is in P shift, the vehicle speed is 0, and the wheel signal line is maintained at a high level. The vehicle navigation multimedia information display unit receives gearshift position and vehicle speed data via the CAN bus and obtains the wheel rotation speed from the pulse frequency of the wheel signal line. As a result, the in-car TV can be viewed normally simply by changing the CAN shift position data received by the vehicle navigation multimedia information display unit to P shift, the vehicle speed data to 0, and the wheel signal line to a high level.

[0021] The normal CAN hardware connection method is for the CAN transceiver in the body control module to be directly connected to the CAN transceiver in the vehicle machine, and to exchange data with the vehicle machine via the CAN bus.
