Ever since I updated my iPhone 6s to the new iOS 10.1.1, I can no longer answer my phone using the phone button on the steering wheel, I can hear them, but they don't hear me. I'm wondering if anyone else is having an issue with this? Apple hasn't fixed the problem yet in a few iOS 10 updates. Funny, it worked fine before I updated. Wish I could undo the update back to the previous iOS. Apple has always been great about update fixes, but this one seems to be taking a while. The only way I can answer, is to actually answer the phone, then press the phone button, not the safest thing to be doing driving!
Thanks,
Tom

 

Try a reset of the phone by holding the home & on/off simultaneously.
Then remove and reinstall the phone to "my car"

I've done this several times, even completely reset the phone, still didn't work right.

 

Borrow another phone
Remove yours from the car and pair another phone and see if that works

Oh, thats an idea, I'll try that. I wish I could revert my iPhone to the previous iOS, it worked fine with that!

 

Apple often signs ipsw's one update back until the next update comes out.

Go to a website like Redmondpie and see if they have iOS Ipsw files available for your phone. They have most devices.

Once you've downloaded the IPSW file you may open iTunes, shift click on update, and update to a previous version of Apple software.

 

Oh, I've thought about that, but don't want to lose my pictures and settings on my phone. If I back the phone up, it will defeat the purpose of going back, right?

 

If you back up your phone the only thing that changes is the iOS software. Everything else remains the same after you upload your information back on it.
