That's what I do whenever there's a phone glitch. Works most times.Sounds like typical electronics connection issue. Remove the phone from Sync and reset Sync to factory settings. Reconnect the phone and hopefully it fixes it.
No hearing aid here.byt where is Bluetooth menu on my 2019 premium mustangNot sure this applies, but I recently saw the exact same thing happen in a different Ford vehicle. I was helping to diagnose the issue and it turned out to be a problem with the owner's hearing aids, his android smartphone, and the way both of those things interacted with the vehicle.
Once figured out, going to the phone's Bluetooth menu and disconnecting the hearing aids fixed the issue. Not a perfect fix, but it worked reliably. And the hearing aid app on the phone was still working with the devices even while disconnected from Bluetooth, so all good there.
I was just thinking maybe the microphone itself has failedWouldn’t that depend on what you asked them to do?
