With the second generation MBUX infotainment system both the hardware and software have changed. Numerous vehicle and comfort functions can be controlled on the infotainment screens in display views. The sizes of the driver and central displays, each measuring 12.3 inches, have been retained. The central display can be operated directly as a touchscreen. Apple CarPlay and Android Auto are now available wirelessly. The appearance can be individualized with a total of three display styles (classic, sporty, discreet) and four modes (navigation, assistance, service, off-road). When a new software update for the GLE becomes available from Mercedes-Benz, a message appears in MBUX. The update is downloaded and installed in the background. The user must then explicitly agree again to the activation of the update.

The voice assistant “Hey Mercedes” is more interactive and capable of learning by activating online services in the Mercedes me App, Mercedes claimed. Certain actions can be performed even without the activation keyword “Hey Mercedes,” including taking a phone call. “Hey Mercedes” also explains vehicle functions upon hearing the “Help” command, and helps when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found, for example. “Hey Mercedes” recognizes the position of the occupants. In addition, other vehicle functions such as the interior lighting or the blinds can now be controlled by voice command.
