    Question Stuttering Bluetooth

    So I just bought a 2012 M3 with Nav package earlier this week. It’s been a dream come true, literally.


    I have one issue though. The audio periodically stutters when using Bluetooth. Has anyone experienced this? I’m trying to search google/forums but so far I haven’t had much luck with a solution.

    Background: I think most BT systems buffer data upon connection. That way any slight/short interruptions in the flow of data are unheard by the listener.
    Hypothesis: the buffer in the head unit is occasionally being “emptied,” which results in intermittent loss of sound.

    What device are you using as the source of the audio data? Smartphone?
    How old is that device?

    Thanks MarcoZandrini but I think I found the solution!

    Since it got worse when I was moving I had a hunch it was a loose connection somewhere. After some research I found that the bluetooth antenna is in the driver footwell. I took a look at it and found that the connector wasn't snapped in. I pushed it all the way in and now (knock on wood) it seems to work!
