Abstract
An automatic identification of the features associated with an audio system for a vehicle based on the selection of the associated bezel (14). The audio system includes a printed circuit board (34) having at least one finger pad (30) thereon in communication with a microprocessor (16). The microprocessor (16) includes programming sequences for various possible features for the audio system. The bezel (14) may have no, one or multiple programming tabs (36) in alignment with corresponding finger pads depending upon the model of bezel chosen. Contact of the finger pads due to the programming tabs will indicate to the microprocessor which programming sequence needs to be initiated to activate the appropriate features corresponding to that particular bezel installed on the audio assembly.
