Anyone having issues with their microphone when making calls? No one can hear you? I did all of the suggestions from

Apple…None of the suggestions worked…however, I did find the answer on my own.! For anyone else having this issue with your microphone on a newer Toyota..(it will probably work on other cars, too)…try this…remove the negative terminal off of your car battery and leave it off for 30 minutes or longer. Reattach the terminal and then it should have reset your DCM in your car and your microphone should be working again. Hope this helps!

Hi sadegh195, 




Thank you for using Apple Support Communities. 




We see that after you use CarPlay, the mic on your iPhone does not work. Sometimes you are unable to hear anything when making a call as well. We want to help. Does the issue only happen with CarPlay or if you are using the iPhone by itself? Please follow the steps here that talk about If the microphones on your iPhone aren't working.


If this issue is only with CarPlay, please look at this article that talks about If you need help with CarPlay.


Reach back out with any questions.


Have a great day!
