Bluetooth & USB audio no longer working, and cannot find an update file (Prius V 2012)

Good evening, whosoever,

About a year ago, I was plugging in a USB drive to listen to the audio files on it when abruptly the USB audio function and Bluetooth audio function ceased to work. Although I can connect my telephone (iPhone SE 2020) to the system and make/receive calls, I cannot play any music whatsoever though Bluetooth or USB. The USB port still supplies power, and the AM, FM, AUX and CD/MP3 functions still work perfectly. How can I remedy this problem? I have looked around the internet, but have found no conclusions except to "update the software."

(Yes, I reseated the battery. No change.)

When I attempted to find the update, I couldn't find a software file to download on the Toyota site nor anywhere else. If updating is the answer, could someone direct me to a link to download it?

Thank you.

Dang. Well, thanks for the reply. I’ll see what I can do.
