That sounds like a frustrating situation with your car's audio system. I had a similar issue with my old car where the Bluetooth connectivity was wonky, and calls sounded like they were coming from a tin can! I stumbled upon an article (

One time, I borrowed a friend's car and noticed how crisp and clear the sound was, unlike mine. Turns out, there was a software update available for my car's audio system that I hadn't installed. Maybe it's worth checking if there are any updates specifically for your car's audio system? Sometimes those updates can iron out these kinds of glitches.
