I'm having the same issue with the entire bottom row of my stereo not working in my 2014.5 Camry. Just by luck (and almost putting my finger through the screen!) I got it to pair my new phone. It was hit or miss for awhile, but now it's completely dead. I was at the dealership today and they said to contact Toyota at 800-331-4331 and let them know about it. If enough people report it they *might* fix it. Of course mine's out of warranty! The guy at the dealership said the Corolla's are starting to have the same problem. This is my 4th Toyota and I expect them to fix it in good faith if all of us are having this issue. They're obviously defective and I think it's definitely a safety issue if we can't pair our phones for hands-free usage, which is now the law in most states.
