Apple Car Play no longer works with iOS 17.1.1

"Apple Car Play no longer works with iOS 17.1.1: It seems that the latest iOS upgrade is not compatible with my 2016 Cadillac XTS to use CarPlay. I have to connect my iPhone 12 mini running iOS 17.1.1 using a USB cable in order to use CarPlay and it was working until just recently. I assume it has to do with the latest update. Has anyone else experienced this issue and if so what is the resolution? Thanks in advance."

Update the Car's Stereo:

Some stereos have firmware updates. So, see if you need to install any, for compatibility purposes.

My iPhone 14 Pro when I use a lighting to headphone jack adapter it shows it’s playing music but no sound comes out the car speakers. Car radio works. Sound and music come out of the phone & Bluetooth headphones work with it, but not the lighting to headphones jack for the car with 17.1.1 update

This appears to be a common glitch for me on *.1.1 updates, there must be some error in the build process. I have 3 CarPlay devices now none work even after factory reset and firmware updates. Waiting for 17.1.2 to come out and betting everything will work.

Honda SUV - rebooted my Honda system, working again

Suggest try that for your vehicle. Might work did for me.

I have an 04 Corolla and never had a problem before the 17.1.1 update. It goes to a cassette player
