Hi,I got an audi Q7 2007 no aux connection ,no usb port , no music bluetooth. 

I just want to play music from my phone to the audio .

I dont want to change the music system in the car but wat can add (ex parrot etc ) to the car music system to play music. 

Any suggestion .

Thanks

This have solved the problem. 
if phone rings via car Bluetooth the music stops, then returns after phone conversation has finished 😁
