Greetings,

I have a 2009 Porsche 997:2 carrera. The car does not have any aux connection in order for me to connect my iPhone to my car and be able to play music etc… as a result, my audio car guy installed a pcm Apple car play upgrade to my pcm. However, he could not for anything connect my phone to my 997.2 pcm and get audio.

He looked and looked with no progress any radio option to select the aux option on the radio itself. Now he told me that I need a PIWIS upgrade in order to upgrade the pcm and add the aux.

Any guidance and or recommendation would be great. I tried everything the aux does not show when you put in a cd player.
