IOS 17.1.2 causes CarPlay to repeatedly connect and disconnect

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

IOS 17.1.2 would not let my phone complete a call, nor answer a call through a "WIRED" CarPlay connection. Nor could SIRI complete a text through the same. Whatever it did to the CarPlay software in the car radio, also caused a problem with our SIRIUS XM Radio reception (software issue) (the radio is a GM Touchscreen radio as supplied in the 2018 Equinoxes)

I had to completely shut the car off, with the phone disconnected to get SIRIUS XM back (reboot the radio).

Doing the "hard reset" fixed the problem (I have an Iphone 11) however, there is no long an Apple logo appearing, just a blank screen while the button is held in. Releasing it allows the phone to restart.

You are welcome.
