Hello. I ask very rarely as i never needed anything)
Out of nowhere, upon starting my car ( 2020 RX 350 Regular) i discovered that people cannot hear me over bluetooth. I can hear callers perfectly, music, navigation sounds works fine. Just when i call someone or someone is calling me they hear nothing. Again i can hear perfectly. Earlier today, when i was driving, everything was working fine.
Oh, i disconnected ( deleted bluetooth device) and paired it again. I rebooted a head unit before pairing my phone again.

Thank you for any advice.

 

I'd check your phone settings in the WIFI volume control... that's a start.

 

thank you for your advice.
Which Wi-Fi volume control are you referring to?

 

Apple iPhone 14 Pro MaxChoose Settings. Scroll down. Choose Sounds & Haptics. To set the volume, drag the slider under RINGTONE AND ALERT VOLUME.

 

Unfortunately, microphone and speaker volumes are controlled by the same button(s) on iPhones. To keep it simple, I would just use the volume buttons on the phone while you are on a call.

 

Thank you very much everyone for commenting.
Yes, correct on the point that during the phone call volume is controlled by volume buttons.
Adjusting a ringtone value while not on the call will do nothing on ones ability to hear or receive a call. When phone is on mute you still can talk on it and most importantly either party can hear you.
In my case no one could hear me while I was able to hear everything perfectly fine.
However situation solved itself. I came home and locked my car. Besides searching on the Internet what would be the issue I was also doing multiple errands around the house and in about couple of hours I went to the car started and everything was back to normal.
Well, computers have a headache too)))
