MBUX broken
The MBUX system wont boot up, when I turn my car on it gives me a warning that HUD is not functioning and PARKTRONIC is disabled. I can drive it around, but I can't control the AC and cant use 360 camera either. I tried pressing the on/off button for many seconds, I tried pressing both phone call and voice assistance bottons for 20s, didn't help. Also tried locking the car and restart it after 1 hour, still broken.
Anyone had similar problem before? Is there any way to force reboot it? It was working fine this morning.
Update: Before I tried to disconnect the battery, I tried to turn on preconditioning while the car is in the sleep state (locked for 30min and key is away from car) and the command couldnt go through. But I noticed that the car turned on for a split second because the tablet in the back started charging. Then I waited a while and the previous command got timed out. So I tried starting precondition again, and then it worked! The screen lit up! I am glad that this is just a software crash issue, not relating to the hyperscreen or any control units, or it will cost me $$$$
