I recently got a 2018 Journey GT at Carvana. Definitely no CarPlay. I thought that all 2018 cars would have it but no. And no NAV too, I tried to buy the option at the Connect website to add it but it's not possible.
But I love the car, besides fuel consumption :-) At least the gas is cheap now.
To use Waze, an app that I really like, I added an 8 inch Lenovo tablet but it's really annoying to charge, deal with overheating, mount, etc. I've been using Android stereos for many years and I found a good one for the Journey, the same that other member of this forum found, I posted my comments in other thread. It's very flexible and it supports CarPlay.
