Apple car play

Pioneer do the best Apple CarPlay head units in my opinion. I'm running a Pioneer head unit (standard not CarPlay) and just needed an adaptor for the steering wheel controls, don't see why it would be any different for CarPlay.

How do you get the screen to fit into the existing space ?

Thanks
