Car is 2012 c220 Today I was playing about with the audio and thought I would have a go at BT Audio and to my surprise it started playing music and as I don't have anything saved on my phone I am wondering where this is coming from. I turned off my mobile data and BT Audio said stream had stopped so I am guessing this is being streamed into my car through the phone. Is this right as I don't know what streaming service this would be coming from. Anyone have any ideas?
