  "textContent": "The invention provides a car multimedia device for automatically switching between an internal device control mode and an external device control mode, comprising a first connection port, a second connection port and a control module for being connected to the first connection port and the second connection port. The control module scans the second connection port to determine whether the second connection port is connected to an external electronic device. When the second connection port fails to be connected to the external electronic device, the control module performs the internal device control mode to control the car display via a car host. When the second connection port is connected to the external electronic device, the control module transmits a master control information of the external electronic device to the car display such that the external electronic device controls the car display via the control module for rapidly automatically switching.",
