1. A connecting device, comprising:
- a first power plug for connecting to a power output port of a vehicle;
a second power plug for connecting to a power input port on an electronic device;
at least one signal plug for connecting to at least one signal output port of the electronic device, wherein visual signals and audio signals are received by the connecting device through the at least one signal plug;
a wireless transmitter for wirelessly transmitting the visual signals and the audio signals to a receiver in the vehicle, wherein the visual signals include video;
a multiplexer for multiplexing the audio signals and the visual signals; and
a modulator having input connections to receive the visual and audio signals via and not via the multiplexer, wherein, when the modulator receives the visual and audio signals via the multiplexer, the modulator modulates the multiplexed visual signals and audio signals onto a predetermined frequency for wireless transmission at the predetermined frequency, and wherein, when the modulator receives the visual and audio signals not via the multiplexer, the modulator modulates the visual and the audio signals not transmitted via the multiplexer.
