If you're in need of an AUDIO knob or button for a GM CD or CD6 radio like the one pictured, you've come to the right place. We carry a large stock of brand new parts for this radio. This is for one AUDIO knob. (The small knob on the right side of the radio face.) If you are in need of several buttons, you would probably be ahead to order the complete face from our Parts>>GM>>Faceplates category.
