The head unit freezes, restarts, or shuts down entirely; the Bluetooth connection drops regularly, and the wireless charger does not recognise the phone. It happens as early as 10,000 to 30,000 km. It is often software, but a hardware fault can be behind it too: the slow response of the navigation and the outdated map are part of the same thing. Cars built up to 2016 still have the first generation (MIB1) head unit, and most of the faults fall on the 2014 to 2016 model years. Intermittent loss of the reversing camera belongs to the same group.
