The big screen on my 2016 X will not work however the car does operate? What could be the problem?
First, have you tried a hard reboot? Press the brake pedal, and hold in both scroll wheels for 30 seconds or so.
If it has truly failed, there are about a thousand components that make up the MCU. Hard to guess what specifically may have failed. You'll need a service visit to find out more.
Hello Mike. After your reboot, RESET your trip odometers and delete all unnecessary Navigation locations. Then reboot again. If this helps, the Problem is your eMMU.
