I just installed the SIR-PNR2 to my Z1 and I see the channels on my display but no volume only on sirius.I have volume on all other Av just not sirius....I have a SIR-PNR1 installed in my other truck so I tryed to switch units to see if the SIR-PNR2 that I just bought was faulty but with the same result.I have checked all settings and did a full system reboot and no VOLUME!! I am have no clue what else to do so if someone has any ideas please help me
