Hello, I've recently bought my MY17 (2016) A3. I've found that I'm missing some things, so inmidiatelly started to look for it In another topic I fight with Auto Hold, but here I would be very pleased if you will give me some informations about AA/Carplay retrofit. I bought that setup: https://pl.aliexpress.com/item/33034294460.html and it looked like quite easy to fit (plug and play, of coarse with new software), but i have a small problem with green plug to be put on MMI. Green one is the same as it was in old usb socket so it was easy to change in big socket taht goes to MMI, but there are also 2 loose pins, and i don't know where to put it. Do you have any idea about that maybe?
