I'm trying to figure out if my 2015 S-550 has Car Play. My friend has Car Play in his Mercedes (different model), and when he connects an iPhone, Waze map and directions are displayed on the main display. He can also see his SMS Messages, an other things on the main display. Can I do that on my S-550? Or do I need to install something? What?

 

Your 2015 does not have Car Play.
