It’s the USB and AUX input out of an E9X from the junkyard. It’s the one thing on my E92 that’s not functioning correctly, and I believe that this part might be the culprit. Now I just need to pull apart my center console to swap it out. Hopefully this will fix the issue and I can use my phone to play music in my car. Sadly, because it’s a 2009, I don’t have bluetooth audio, just bluetooth calling. I believe that bluetooth audio was added for the 2010 MY; the M3, being a 2011, has bluetooth audio.
