Audio/video expansion device and vehicular audio/video system using the same
First Claim
1. A vehicular audio/video system, comprises:
- an expansion device for generating an output signal;
an output device for receiving the output signal;
an optical disc device for generating a first input signal to the expansion device;
a detachable media storage device for generating a media data to the expansion device which processes the media data into a second input signal; and
a handheld communication device for generating a communication data to the expansion device which processes the communication data into a third input signal;
wherein, the expansion device selects the first input signal to be the output signal under an optical disc mode, selects the second input signal to be the output signal under a media play mode, and selects the third input signal to be the output signal under a communication mode.
