As a long-standing supplier of premium automotive components for the S-Class, I’ve spent years diving into the details of what makes Mercedes-Benz’s flagship sedan’s entertainment systems stand out from the crowded luxury segment. Many clients come to us asking, “What exactly goes into the infotainment and entertainment suite of an S-Class?” It’s not just a touchscreen and a few speakers—this is a system engineered to turn every drive into a immersive, personalized experience, tailored to the way modern luxury drivers live. Let’s break down exactly what’s included, straight from the perspective of someone who’s worked hand-in-hand with Mercedes’ engineering teams to bring these systems to life. S-CLASS
First, the core of the S-Class’s entertainment setup is the MBUX (Mercedes-Benz User Experience) infotainment system, and let’s be clear: this isn’t the generic MBUX you’ll find in a C-Class or E-Class. For the S-Class, it’s scaled to match the car’s ultra-luxury positioning. We supply a range of components for this, from high-resolution touch sensors to the processing modules that power its lightning-fast response. The main display is a 12.8-inch OLED touchscreen that curves seamlessly into the dashboard, creating a nearly uninterrupted, high-gloss interface. Unlike older touchscreens that required firm presses, this OLED panel is calibrated to register light taps and even swipes like a smartphone, which is a game-changer when you’re trying to adjust navigation or audio without taking your eyes off the road. What makes it unique here is the “zero-layer” design—there’s no cluttered menu screen that pops up when you turn the car on; your most-used functions (navigation, audio, climate) are front and center, so you don’t have to dig through submenus. That’s not a random feature—it’s a safety-focused tweak we worked on with Mercedes, because distracted driving is a top concern for luxury buyers.
Then there’s the second display, a 12.3-inch digital instrument cluster that sits behind the steering wheel. This is where the driver gets all the critical info, and it’s fully customizable. You can switch between views: a classic analog-style speedometer and tachometer, a “navigation” view that overlays turn-by-turn directions directly onto the speed readout, or even a “assistance” view that shows live feed from the car’s driver aids (like blind-spot monitors or adaptive cruise control). For rear-seat passengers, there’s an optional 11.6-inch dual-screen setup, mounted on the back of the front seat headrests. These aren’t just basic screens for watching movies—they connect to the MBUX system, so you can sync your personal phone apps, stream content via apps like Netflix or Amazon Prime Video, and even use them to adjust the main climate control or navigation for your own rear-seat trip. We supply the high-definition backlights for these rear screens, which deliver crisp, vibrant images even in bright sunlight—something that’s easy to overlook, but essential when back-seat passengers are using their screens on long highway drives.
Next, the audio system, and this is where the S-Class really separates itself from the competition. Standard on most S-Class models is the Burmester® Surround Sound System, but for the true audiophiles, there’s the Burmester® 3D High-End Surround Sound System that we’re proud to supply parts for. This system isn’t just about lots of speakers—it’s about precision placement and calibration. The 3D version has 31 speakers total, including ones in the headliner that create that immersive, three-dimensional soundstage. It uses a 1,750-watt 31-channel amplifier, and here’s the clever part: it’s integrated with the MBUX system’s GPS and climate controls. If you’re driving through a tunnel, the system adjusts the audio equalizer to compensate for the change in ambient noise, so your music stays clear. If you’re using the climate control to cool the front seats, it can adjust the sound balance to direct more audio to the front, since that’s where the occupants are seated. For rear-seat passengers, there are also individual audio controls, so someone in the back can listen to a podcast on their own headphones without disturbing others. We supply the speaker drivers, the amplifier modules, and the acoustic tuning components that ensure the sound doesn’t bounce incorrectly off the S-Class’s plush interior surfaces—like the leather seats and wood trim, which can easily muffle or distort sound if not calibrated properly.
One of the most underrated parts of the S-Class’s entertainment system is its integration with personal devices and smart home tech. MBUX has “Hey Mercedes” voice control that’s way more advanced than basic voice assistants. You don’t have to say a specific command, like “Hey Mercedes, turn on the AC”; you can just say “I’m cold” and the system will adjust the climate. It’s context-aware, too—if you’re in the middle of a work call, it’ll lower the audio volume automatically, and if you’re navigating to a restaurant, it’ll even suggest a parking spot nearby. We supply the microphone array for this voice control, which has 7 microphones total (including ones in the sun visors and rearview mirror) to pick up your voice no matter where you’re seated, even if there’s road noise or the AC is running. You can also connect your phone via Apple CarPlay or Android Auto, but unlike many cars where CarPlay is an afterthought, the S-Class’s MBUX integrates it seamlessly. You can control CarPlay apps directly from the main touchscreen, or use “Hey Mercedes” to send a text or make a call through CarPlay, without disconnecting from the system. And for tech lovers, there’s also wireless charging pads in the front and rear center consoles, plus USB-C ports for every seat—so no one’s fighting for a charger on long trips.
Then there’s the rear-seat entertainment suite, which is a big selling point for buyers who use their S-Class as a chauffeured vehicle. Beyond the two headrest screens, there’s an optional rear-seat remote control that lets passengers adjust their own entertainment settings, instead of having to ask the driver to change something. The system supports streaming via Wi-Fi 6, which is faster than most home Wi-Fi networks, so you can watch 4K video without buffering. It also has an HDMI input, so you can connect a gaming console or laptop for work or entertainment. We supply the Wi-Fi modules and the remote control components for this, ensuring that the connection is stable even when driving at high speeds, since Wi-Fi can drop or slow down on bumpy roads. Another feature is the “Burmester® Room Sound” mode, which adjusts the audio to sound like it’s coming from a home theater, specifically optimized for the S-Class’s rear seat area—this is great for watching movies on long flights, or just relaxing on a weekend drive.
I’ve worked with a lot of luxury car brands over the years, but the S-Class’s entertainment system stands out because it’s designed around how people actually use their cars. It’s not just a list of features; it’s a system that adapts to the driver and passengers. For example, if you’re a parent driving kids, the rear-seat screens have a “child mode” that blocks mature content and limits screen time, while still letting them watch their favorite cartoons. If you’re a business professional, the rear-seat screens can display your work calendar and let you take video calls, with noise-canceling microphones built into the headrests to make sure your call is clear. We’ve heard from multiple Mercedes engineers that the goal was to make the entertainment system “invisible” when it’s working well—you don’t notice it, it just does what you need it to do, without any glitches or confusing controls.
Now, as a supplier, I can tell you that every component of these entertainment systems is built to the strictest quality standards. The touchscreens are scratch-resistant, so even if you’re carrying keys and accidentally brush the screen, it won’t get damaged. The speakers are sealed to prevent moisture from getting in, since the S-Class has a panoramic sunroof that can let in water during car washes, and the audio system is tested to work in extreme temperatures—from freezing winters in Canada to hot summers in the Middle East. That’s why so many luxury buyers trust these systems: they’re not just high-tech, they’re durable, too.
