1. A method for manufacturing an automotive sound system comprising the steps of:
- installing a main board into a chassis, said main board performing audio functions common to a group of players for playback of pre-recorded media, said group comprising a cassette player and a compact disc player;
selecting a player from said group of players for completing said automotive sound system;
installing a mechanism sub-assembly corresponding to said selected player into said chassis, said mechanism sub-assembly including a mechanism microprocessor for controlling a player mechanism;
installing a bezel sub-assembly corresponding to said selected player into said chassis, said bezel sub-assembly including a bezel microprocessor responsive to operator inputs and controlling a display for said selected player; and
interconnecting said main board, said mechanicm microprocessor, and said bezel microprocessor via a common bus.

Abstract
An automotive sound system achieves manufacturing flexibility by joining a common chassis which implements radio functions with additional boards that are specific to either a cassette, CD, or DAT mechanism which is to be joined with the radio as an integral unit. Each board is controlled by a microcontroller and the separate microcontrollers are connected by a shared bus.
