High pitched noise from center infotainment stack
Exactly. When I measured the frequency that my car was emitting, I started looking up the age groups that can hear in that frequency range. In each of the loaner X5's I've had with the color HVAC display, the noise was present but with varying levels of intensity. I'm sure most of the X5/6's have this issue with the color display but only a small group of people are actually hearing it.
