Yes. The car can read your texts when you’re not connected to CarPlay this way.Yes, and I remember reading somewhere that this also let's the car see your new text messages.
However, I found it a little annoying the way it alerts you to every text that takes up the whole infotainment screen until you acknowledge it so I turned the notification function off.
There is another thread about the clock not syncing all the time where the notifications have also been discussed. While the notifications will probably keep your time in sync, it’s not the only way the unit syncs it from your phone. My time has stayed in sync even after removing the notifications though I still have no idea what prompts it to sync ?♂
