I have a Prius c 1 2013. I always have a usb thumb drive with mp3 installed in my car. Can i connect my phone using Bluetooth for phone call while playing mp3 with usb thumb drive? Both of them are controlled by media button.
It was made to function exactly as you describe on my 2012 model 3. Assuming it will also work on a model 1. The car will mute the music when a phone call comes in and on the 3 present you with a screen on the display allowing you to accept or reject the call. Or with a trim level 1 like yours, you can use the button on the steeling wheel to accept it.
