Multimedia system

GLBS in Sport and AMG Line specifications come equipped as standard with smaller, 7.0in screens for the MBUX infotainment system and digital instrument display. Add the Premium package that was fitted to our test car, though, and those screens are upgraded to 10.3in displays. You’ll also gain an uprated, 225W sound system and MBUX augmented reality for the satellite navigation. This latter upgrade adds digital navigation prompts over a video feed from the camera to help you to navigate roundabouts and the like. It’s a smart-looking touch, although our testers soon found they switched it off.

Otherwise, the system’s operating software is as intuitive to use as ever. The trackpad on the centre console can take a bit of adjusting to, but the screen itself responds to your touch anyway and the thumbpads on the steering wheel work well enough. The graphics are pretty slick, too, and the sound quality from the Mercedes Advanced sound system is really quite good.
