The CarPlay rumor mill has the 2016's as maybe for late model builds. However, in a couple of months from now the 2017's will ready for pre-order. If anything mostly likely the 2017. Knowing FCA, do not count on anything.
As for previous model years for the 2014+, nothing is going to work with CarPlay.
Best for now.
