Hello
i need to retrofit CarPlay on my Cayenne 2011. It has PCM3,1. For this kit i need aux port for the Sound. I dont have original aux port, so i Think i need to retrofit aux port in radio first? Do i need aux + cooding aux, or has anyone tried this problem?
has anyone tried to retrofit aux to similar car?

this is my CarPlay kit: https://www.ampire.de/Smartphone-Integration/PORSCHE/Retrofit-Systems/AMPIRE-smartphone-integration-for-Porsche-PCM3-1.htm?shop=ampire_en&SessionId=&a=article&ProdNr=L DS-PCM31-CP&p=59916




i just bought this kit for aux, but its for CDR31 - Will it fit my pcm3.1? Link—>
