[Mitch AC DC]

Hi all, just noticed recently {after a years driving}. a warning? notification? sound. happens randomly, nothing shows i can see on dashboard!. sounds like a "Quack"-"Quack" or "Buzz"- "Buzz" sound?
suggested Bluetooth Mobile phone related emails? messages?. Vicinity warning?
Answer or suggestions welcome. Thanks

Edit 18/Dec/2024:
Panic over everyone, driving new car home, with dashcam dangling from sunblind, and son siting in passenger seat. He noticed the "Quack" "Buzz" was coming from the Dashcam, so no problem with car. Problem now is, why is the dashcam "Quacking"???

It could be something to do with the AC. En route to France mine made similar noises. I only noticed it as the radio was off and the car was stationary. It was quite a hot day, it didn't last long and I haven't heard it since. The noise was just behind the dash.
