People can NOT hear me when I make, or answer calls in CarPlay.

When I call someone or someone calls me, they cannot hear

me, but I can hear their voice very clearly.

I have a Lexus 250h, 2020. The CarPlay was working fine until

I updated my iPhone to IOS 18.

I am using the WIFI hot spot in my car (ATT service). I can

make calls and receive calls while using Bluetooth and the caller can hear me. BUT

when I plug in the iPhone and start CarPlay the Bluetooth turns off.

All the other features work fine in CarPlay but not Siri or

phone calls. When I ask Siri to make a call the cars display panel shows the microphone

is off. The CarPlay screen does not show my phone connected.
