I recently bought a 987.2 Spyder. One of the things I never quite understood was the operation of the PCM. I imagine I have a lessor PCM as there are no AUX and Ipod outlets in the armrest.
But my question is about phone connection. There are buttons for phone off and on but the radio says it's not available. Is that because all the PCM models have the same sutface configuration with different levels of skill inside? Or is there a possibility that I can get phone operation out of the unit?
thanks
