An entertainment system for a vehicle accommodating a passenger with a personal electronic device executing a screen sharing application. The entertainment system includes a network onboard the vehicle and information processing devices connected to the network. Each device includes a data processor, and at least one including a display monitor and a screen sharing server executed by the data processor of the device with the screen sharing server being receptive to a display data stream communicated over the network to the screen sharing server by execution of the screen sharing application of the portable electronic device. The display data stream is communicated after pairing of the screen sharing application the device.
