I am having the exact same issue on my 2014 Toyota Camry! The lower portion of the touch screen to add or remove Bluetooth device is not working. So I am not able to pair my new Phone after the old one died.
My 2014.5 Camry has never allowed me to adjust the bass in my audio, which I find excessive. I thought I was simply not working with it, and now I find that many owners are having this problem. I used to be able to add new users to my system, but now that does not work, either. With so many users having this problem I agree that Toyota, if they already knew this was an issue, should do good faith repairs.
If only the bottom left is broken, you can remove all phones from the list, then hit the phone button on the side of the screen, which will give you a way to connect one phone by clicking a button higher on the screen by an inch or so.
Still sucks, but at least we got one phone connected. Hope that remove button keeps working for us!
Recalls are only for safety related items, which the radio is not considered a safety item. Now, if enough Toyota owners have this issue and make their voice heard, Toyota may issue a warranty extension for this concern.
Hands free phone operation is a safety issue, it is state mandated in most states and is, therefore, an issue that must have a recall without warranty involved. If the buttons don't work properly, the phone can't be paired.
