We installed the CarPlay retrofit for our recent model Mazda CX-5 and it does exactly this. The CarPlay interface completely takes over the vehicle interface and the buttons are mapped in a way that makes sense: home takes you to the home screen/springboard, nav opens Apple Maps or whatever navigation application is currently running, and music opens whatever media application was last selected. Most importantly the voice assistant button on the steering wheel triggers Siri. Best $250 I’ve ever spent and the utility of this keeps improving as more apps add CarPlay support.
