2014 IS250 awd, Android Sony XPeria....
As soon as my phone/car pair up over Bluetooth, the car starts to play music from my phone! This happens even if the Music App on my phone is not running.
I've spent at least two hours searching this forum, and reading through my Owners Manual, but cannot figure out how to stop this.
Has anyone encountered this, and if so, were you able to stop this from happening automatically?

 

Is your audio source set to Media/Bluetooth? I believe setting it to that will, with some phones, start the native music player. You could try just changing to radio or turning the audio system in the car off.

 

Thanks again, problem solved through your advice.
In attempting to go into the source as you suggested, I found the ordering of the source screen, which was set to Bluetooth first. I changed it to AUX first, and now the phone connects but doesn't play automatically. I suspect that if I connect something in the AUX it will start to play from there, but I have no intention of using the AUX.
Thanks again.

 

Cool, glad it was a simple fix!
