A wireless communication system for a vehicle includes a seat or overhead video display unit, a control and audio unit that is associated with and located remotely with respect to the video display unit, a first wireless transceiver associated with the video display unit, a second wireless transceiver associated with the control and audio unit, where the first and second wireless transceivers are linked together for communication. The video display unit receives audiovisual content and splits audio content for transmission to the control unit. The control unit can similarly transmit control and selection information to the video display unit.
