I’ve been told 1.2 at the earliest. The right hand screen has a non standard size which limits the CarPlay screen to a perfect rectangle inside the screen.
CarPlay does work with dual-screen setups with a main screen and instrument cluster, but there could be a neat trick to it. I think Lucid wants the right hand nav screen to be the instrument cluster in CarPlay and the lower screen to be the controls. This would mean you adjust CarPlay on the lower screen and the upper one shows nav, tracks, etc. This may be why it is delayed, because CarPlay is otherwise quite straightforward to implement.
