Mercedes Benz CarPlay upgrade

Question

I have heard rumours that if you have a 2016 or newer Mercedes there is a Mercedes factory upgrade kit at extra cost and installation that will give you carplay. I'm thinking of upgrading to a 2016 sl model and CarPlay would be very important to me. Could anyone give me some insight or experience with this please? (I'm new please forgive me if I don't understand where to search first.)
