I haven't experienced that exact issue in a Honda Clarity, but I've had my fair share of Bluetooth quirks. One time, I was driving and chatting away when suddenly my friend mentioned this weird buzzing noise. Turns out, it was coming from my car's Bluetooth connection!We did some troubleshooting and found that
it was interference from another device nearby. Once we moved away from it, the call quality improved. So maybe there's something in the car's setup causing interference?It might be worth checking if there's anything in the car's audio system or surroundings that could be causing the noise.
