I see a lot of people installing MMI units to get Android Auto/Carplay functionality. I'm not interested in Carplay, but would like to add Android Auto. I've looked at Bimmer Tech and Road Top, but I don't see anything that is compatible with the 2019 i3. I take it there were some changes made to the head unit over previous models? Does anyone have Android Auto working on their 2019+ model, and what method did you use to do so?
