There are several (original) Uconnect head units on which CarPlay and A#ndroidAuto is present. In could be also a case that this feature is present, but not activated. (Normally on 500L 2018 those have an original navi, i don't know about other 500 series) In case the feature is present but not activated- it's hard but possible to activate it. At least, one can buy some software and instructions for that on italian e-bay for 60EUR. In case CarPlay is physically absent the only solution could be to buy an aftermarket head unit, or another original head unit with Carplay.... And, of cause, all these CarPlay systems are wired, all the magic boxes making wireless Carplay form wired will not work at all.
