PMX-3 has no SiriusXM audio output

My PMX-3 has no output when SiriusXM is selected.

The PMX-3 source unit supports Satellite Radio by using the optional SiriusXM™ (SXV300) tuner. The PMX-3 repurposes the Auxilliary inputs to use the SiriusXM signal.  Use the below procedure to use the SiriusXM satellite tuner:

 

1. Connect the SXV300 DIN cable to the PMX-3 cable labeled SIRIUS XM INPUT	2. Connect the PMX-3 RCAs labeled SIRIUS XM OUTPUT to the PMX-3 RCAs labled AUX OR SIRIUS XM

 

3. Momentariliy press the SRC button to change the source input

4. Use the ROTARY ENCODER to cycle through the sources:
     (FM > AM > WB > USB > AUX > BLUETOOTH > PANDORA > SIRIUS XM).

5. Push the ROTARY ENCODER to select SIRIUS XM
