When I worked for an Auto maker (left 2 years ago), the cluster was an independent system from infotainment. They could follow messages from each other on the bus (it wasn’t CAN bus, we’d moved on from that) but basically there wasn’t a way for CarPlay to talk to the Cluster.

I’m willing to bet that the soonest any large OEM could offer CarPlay 2 would be next year. The development process is just too slow to turn around something.
