ADD-ON CD CONTROL KNOB PART#USBCDKB


The USBCDKB allows the USBCD1 or USBCD2 to become truly universal.  By separating the audio and the control function, the USBCD1 and USBCD2 can NOW be used on any radio factory or aftermarket by outputing the audio into a 3.5mm AUX jack and giving control of the track foward, track back, play, pause, and even output gain control for level matching. 

The USBCD1K and USBCD2K comes with this knob.
