Abstract
A portable plug device for use in a vehicle is disclosed for enabling wireless transmissions from an audio source, such as an mp3 player or the like, to a head unit of a car stereo for reproduction of the audio content over speakers in the vehicle. The portable plug device includes a cord suitable for being attached to the auxiliary unit of the stereo head unit, or another location integrated in the vehicle which controls audio functions. In one configuration, the portable plug further includes a wireless transceiver for sending and receiving data and control signals to and from an audio source connected to a second wireless transceiver. The portable plug device can be used to receive control signals from the stereo equipment integrated in the vehicle so that an occupant can control features such as volume, skip track, pause and stop by using the audio controls integrated in the vehicle. In another configuration, the portable plug device includes a microphone to enable the occupant to have a telephone conversation hands free using a telephone compatible with the wireless standard implemented in the portable plug device. In still other implementations, an occupant can use the portable plug device to receive audio content, and if he or she receives an incoming call, the speakers are muted and the call is taken. After the call is taken, the occupant can resume listening to audio content from the audio source over the vehicle speakers.
