I have a 2016 Avalon. Have had Bluetooth problems almost since I bought it. Toyota has replaced the mirror as that's where the microphone is. The next time they replaced the radio. I am having problems again. IE - Call Dana comes out tuning to channel 82!!! (Yes, I have done the voice recognition training.) I have made a call directly from my phone and then tried to carry on a conversation through Bluetooth. I can hear my party beautifully. They, however, cannot hear me. What is driving me crazy is that it might work for several days/weeks and then it acts up again. I stopped by the dealership yesterday to make an appointment to have it looked at since it was acting up the previous three days. Naturally today it is working just fine. Has anyone else experienced this?
