Looking to modernize the ZHP a bit while hopefully avoiding something that looks super out-of-place. What is currently the best head unit to get Apple Carplay in a ZHP? I've seen the Avin Avant 4 and like how it looks in the car. Is there a better option out there? And for the Avin, is it worth paying $60 to upgrade from the PX30 CPU to the PX6 CPU? I would appreciate any recommendations!
