Hi again,
My 6 series 2016 model has ID4 NBT (non evo) and I am planning to retrofit Apple car play. I have heard it can be done by installing an MMI box. By reading a bit I understand that MMI works using the AUX, meaning that you can't listen to car's radio or multimedia at the same time with car play. Also there is a very bad call audio.
There is someone here in the UK that said he can update my ID4 to ID6 3 tile system (without changing the screen... he will be changing something not sure what). ID6 will come with with car play losing car's built in nav but I will be able to navigate using car play and apple maps (or any other car play nav). Everything audio wise will work along with car play.. it will be like the original ID6 except the fact that car;s nav won't work.
Not sure what to choose, I would prefer to just long press a button and go whenever i like to car play but he tried to persuade me from it saying MMI is rubbish.

Thanks
