Using the Audi MMI is painfully clunky, inconsistent, and riddled with subscription-locked features. At this point I just immediately wait for CarPlay and avoid touching anything in the car’s native OS.
Honestly they could probably just save a lot of development time by just having a dumb monitor / audio setup that you’re plugging into.
EDIT: Oh, and the Messages.app on macOS makes me pine for the days of iChat.
