I fitted an AliExpress 8 inch version to my 2016 A6 quite easy to fit bits of dash to come off and glovebox out. But and it's a big but the Android software is rubbish. It's supposedly android 10 but it's slow and clunky. Every time you leave the car it turns off so it's reboots when you get in. So wait for a reboot then you gotta select a song or playlist again. No resume function at all!
