I need some help with an integrated circuit for my 2008 Beetle. This is for the radio head unit. A cluster of buttons on the radio console do not work (most frustratingly the disc eject). I believe I have traced the problem to the circuit with the buttons (you can see the non-functioning buttons surrounding the volume dial). The red circle represents the missing element and the blue circle represents what I believe to be the element that is missing.

As you can tell from that last sentence I am a little outside my league on this. Here are my questions:
* What is the black piece inside the blue circle?
* Is it what is missing from the red circle?
* Where /How do I buy a new one?
* Can you give me any information that would help me?

Thanks Everyone!

Thank you @oldturkey03 !!

I measured the diode/transistor, the dimension of the ‘box’ are 2.88mm x 1.55mm (A&B from link).

I measured the G&L of the missing diode/transistors. It appears the G is 1.3 and the L is 0.65 so I believe it would be SOT323.
+

* What are my next steps?
+
+
* Do the dimensions indicate it is a transistor or diode? I am uncertain.
+
+
* Will purchasing one and soldering it on solve my problem?
