My MMI has gone down. My screen is black and won’t turn on. On the cockpit it just says initialising on the nav and phone etc. i have no Bluetooth , sat nav, parking sensors, USB ports don’t work. I called my local garage and they told me that the 5g masks have crashed the system and they are waiting for an update. But it only seems to be my garage that knows of this problem. Is anyone else having the problem?
