Head Unit MOST Pins Pushed In - No Warning Tones or Sounds
Just a heads up in case someone has the same issue installing the AVIN or any other procedure that involves removing and/or re-installing the head unit plug.
2011 E93 M3 Top HIFI system.
I had to bring it to the dealer, it took them a while to figure it out.
Turns out the MOST Fiber Pins coming out of the back of the Radio were pushed into the head unit. They were able to take the radio apart and push them back out. So now I know somehow the AVIN connector/splitter that plugs into the head unit with the MOST cable moved to it, somehow pushed the head units MOST connection in.
Been very frustrating, now it makes sense.
Picture included I hope this helps someone, if you know other places to post please do.
Thank you,
