Abstract
An automotive multimedia entertainment system includes an integrated rear seat entertainment module in which audio signals coordinated with video entertainment devices in the rear seat can be reproduced using the vehicle's audio system. Multiplex control signals between an audio main control unit, rear seat entertainment module, and CD disc jockey allows free selection of sources for single and dual play modes. By sharing an external audio input of the main control unit, between the rear seat entertainment module and the CD disc jockey, a single version of the main control unit can be used in vehicles either with or without rear seat entertainment modules or CD disc jockeys.
