I finished installing this yesterday in my 06 997 c2s with bose and cd changer

I took the fiber optic cable that runs into the PCM and put it into the Dension CDC side, then ran a cable from the Dension car side and put it into the back of the PCM

The car picks up my bluetooth, it reads the songs from the bluetooth, recognizes that I have AUX in, but no music through the speakers

I have Dip switch setting 1,2 up, 3, 4 down and 5,6 up if I remember correctly

I can verify the software ends in 56, the bypass works just fine, I can navigate to the menu and see the cd changer, BUT NO SOUND

What could be the issue? Did I do something wrong?
