As of this writing CarPlay still does not support Satellite view in Apple Maps, regardless of the setting you have chosen in iOS. Satellite would be useful and valuable and CarPlay and cars are capable of it resource wise as Google Maps supports it easily and as others have noted even native Google Map Satellite view in Audi's is very popular. Thankfully, unlike native systems, as soon as Apple does support it, it will be available for everyone without needing a subscription or a new car. If will most likely come with the new iOS version which will be demoed in June or the following year at the latest.
