Thanks FellasOnly if your audio is set to Bluetooth. If it's set to Spotify, you get nothing.
Having said that, on my Samsung S22+ I can customise certain applications to always play alerts on the phone's speaker, regardless of what I'm playing in Tesla Audio. It's in Settings -> Sounds and Vibration -> Separate app sound. I've set up Waze, Uber Driver and Messages to always play on the audio device 'Phone'. I never ever want to miss an Uber ping because I was listening to in-car Spotify!
