The problem with CarPlay in my Ioniq 5, as I detailed in my sibling reply to the post you replied to, is that it doesn't inform the car's own nav-based features like the dashboard directions or the HUD navigation arrow. If I use CarPlay nav I simply don't get those.
I think Chevy is going to Android's whole-car auto system, not just Android Auto. In that system phone based nav probably does do things like inform dashboards and HUDs. And I think Apple has a CarPlay version out or coming that has similar capabilities. Only, Chevy and probably any other manufacturer is not going to make a car that wires two systems all the way through the car.
So I think it's not gonna be just Chevy, and since Android has more design wins announced than Apple as well as probably the brighter future outlook for market share (by way of being hedged across multiple sources) I think you might be looking down the barrel of either this standardizes, or Apple's out.
Just keep in mind the tradeoffs. For example, I was thrilled to get CarPlay in my Ioniq 5 until I realized A) it's wired, as I guess there's some exclusivity deal Apple has for wireless in cars with their own nav, and B) I lose features like the HUD-displayed navigation arrows, since that only works with native nav.
Upshot is I end up using native nav and really only use CarPlay for phone-based audio apps. I've only had the car for a few weeks, so maybe I settle into a different pattern long-term but I doubt it. I bought it for stuff like HUD-based nav, so having it be either/or probably means no CarPlay.
You would think, but as soon as I start looking at Bolt EUV's Chevrolet decides to never get my money with their newest announcement[0]
