This is definitely an Infotainment issue in the 2024. My iPhone works with CP in my wife's 2021 Acadia. In my new truck, the infotainment systems shows "white" wifi icon which means my phone is connected via wifi. It also shows the "green" icons, which means I am connected via bluetooth. On my phone, I show I'm connected via wifi "myChevrolet" and bluetooth "myChevrolet" and lastly under the settings, I see CP is connected to "myChevrolet".
On the Infotainment system, AA and CP are both grayed out. If I tap the CP icon, it brings up a window with "connect". If I tap connect, its says "do you want to disconnect iPhone?" Grrrrr No! I want you to let me use CP with my currently connected iPhone!
I've tried all of your solutions. CP worked once, on a random day while driving, and has never worked again. I've also tried using my wife's iPhone connecting to my truck with the same results. How do we know Chevrolet is actively working on this?
