Some of you may already know about this feature. I had my center screen mysteriously go blank on me. I reviewed the Mazda User Manual and didn't see anything obvious that could cause it. It started working (again mysteriously) a day or two later. Thought the display might be flakey. Took the the CX-50 to Mazda service today for a different reason and mentioned this to the service advisor. He showed me that if you happen to press down on the volume / mute button for greater than 3 seconds, it turns off the display. Apparently it is for situations where the driver may not want passengers to see info on the display (like an Uber driver). Anyhow just sharing in case this happens to any of you.
