CarPlay on IOS 17.4 not working properly

My wife’s iPhone is still working on 17.3, but mine after the upgrade to 17.4 is not. I can’t get sound control on steering wheel or infotainment knob control. I have already tried forgetting Bluetooth & CarPlay, and also reset the infotainment. I have a Camry 2023 with cable CarPlay. Any one knows a solution?

iPhone 14 Pro, iOS 17

GAWD, what a pain in the...

Same issue here where, since update, phone on CarPlay displayed a black screen that lit up only for notice of iOS devices left behind and sms received after which it returned to black.


Yesterday morning, without any of the protocols listed to remediate this, all things being equal, CarPlay lit up full functions on!


Confirmed today, all good!
