pats911 runner

Hi, I have a 2009 911 C2 (997.2) which has no audio inputs. I want to add an input that let's me plug in my phone and play spotify, etc. through the car's system. After some research, I learned that I may be stuck and can't upgrade my Porsche audio system nor can I add an audio input. Does anyone have any ideas on how to steam music through a wired input if one doesn't exist today? Note that's I don't want an FM transmitter solution. Also note that I have a Bluetooth phone attached to the car but that Bluetooth audio channel can't be used for audio. Just the phone uses Bluetooth. Any ideas appreciated to get custom music piped into my drive! Thanks!
