Upgrade of system

Hi

My wife and I have just bought a 2014 (September) new C4 GP. I'd ideally like to make use of Apple's CarPlay function but am missing the button on the steering wheel to do that so I have a couple of questions.

1) On that model is it possible to use CarPlay
2) If not, is it possible to get the phone to mirror to the touch screen display in the car?
3) How to voice dial (start Siri) when using BlueTooth?

Thanks for any help
