Why is my radio making a beeping noise

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Ah, the mysterious beeping radio—it's like your car's trying to communicate in Morse code. In your 2013 Toyota Avalon, this could be a few things; possibly the the chime for the key being in the ignition? Or if it's smart key it will chime until you take the key out of the car once the door is open. If it's beeping while driving and the radio isn't working, it could be in the head unit itself. The real question is; is the radio operational? Give us a call at 877-913-1554 and we can talk through it have yoy senda recording of what the symptom is!

In addition to Bo's valuable insight, a question I have is - is this an original Toyota Audio unit or has it been replaced by something different? It sounds almost like an aftermarket audio unit may be installed. Either way, seek help near you.
