    Hi Friends,

    2017 Prius prime premium owner since the beginning. Great car!

    I am having an issue with sound quality when speaking to someone via Bluetooth. The person receiving my call says that the sound quality is extremely low, and has a buzzing sound. I’ve never had this issue before in 7 years of ownership.

    After some research, here is what I’ve done to rectify the issue:
    -downloaded and installed latest software/firmware from Toyota website
    -disconnected 12v battery for 30 minutes
    -unpaired and deleted Bluetooth phone from car on multiple cell phones, same result.

    Is there anything else I can try?
