Abstract
A vehicle audio/video media system includes an adapter apparatus in electrical communication with an audio/video head unit. The adapter apparatus includes a digital input receiving digital audio/video content from an external source. A digital-to-analog converter is coupled to the digital input and converts the digital audio/video content into analog audio/video content. An output device is coupled to the digital-to-analog converter. The output device transmits the analog audio/video content to the audio/video head unit.
