On the 2013-2025 Mercedes-Benz G-Class, both the older COMAND NTG5 system and the newer MBUX system in the G-Class experience random freezes, black screens, and spontaneous reboots. The harsh vibration environment of the G-Class body-on-frame chassis may contribute to connection issues at the head unit. Navigation, audio, and backup camera all become unavailable during these events.
Perform a soft reset by holding the power/volume knob for 10 seconds. Visit the dealer for software updates — Mercedes regularly releases patches. If persistent, the head unit may need replacement under warranty. Ensure the vehicle has the latest map and firmware updates.
