The faceplate warning tone is annoying as hell I know turn off the unit and hold the multi control button down till clock set appears, turn the knob till warning tone appears and press the knob to turn it off.
then rotate the knob till aux2 apears and press in the knob to turn on aux2 so you can now select it with your source button as you would aux1, cd, bt, or radio.
Hope that helps
