Hi , so I have a 2010 audi avant , my audi does not seem to be compatible with my iPhone xs max. I cant seem to see my content on my iPhone through the system, I tried one Bluetooth mmi connector but it was a cheap model and didn't allow me to control phone through my mmi unit. just played music like a aux unit. has anyone overcome this problem? is there any Bluetooth mmi connectors that allow complete control of the phone via the MMI head unit ? I cant even change the headunit as its intergrated into the car.
