XTRONS Expands Its Linux Screen-Replacement Range: 12.3" QUB for BMW & 10.25" QUM for Mercedes-Benz

12.3" 2K QLED (2400×900) · Fully Laminated Display · 10.25" QLED (1920×720) · Allwinner T113 Industrial Chip · Cold Boot ~3 s · Exclusive XTRONS UI · Live OTA Updates · Plug-and-Play, No Wire Cutting

XTRONS is extending its proven Linux fast-boot car stereo family with two new screen-replacement fitments: the 12.3" QUB series for BMW and the 10.25" QUM series for Mercedes-Benz. Compared to traditional Android systems, which often suffer from slower boot times and high memory overhead, these Linux-based units deliver near-instant responsiveness, ultra-fast boot speeds, and remarkable long-term system stability. Built on this stable closed Linux architecture with an Allwinner T113 industrial-grade chip, these new models pair high-resolution panels with fully laminated touch technology, XTRONS’ exclusive custom user interface, live OTA firmware support, a robust metal body, and wireless CarPlay/Android Auto — all while keeping every factory function intact.
Quick Answer: Why Choose the XTRONS Linux QUB & QUM?

Here is why the QUB and QUM stand out for BMW and Mercedes owners:

Superior Speed & Efficiency (Linux vs. Android) — While Android systems offer a rich app ecosystem, our lightweight Linux OS is purpose-built for speed and stability. It boots up in just ~3 seconds, offering a streamlined, bloat-free experience with instant audio playback and seamless long-term performance.

Flagship Display & Fully Laminated Clarity — The QUB brings true 2K QLED (2400×900) to the BMW dashboard. It features full lamination (bonding the display and touch panel into a single piece) to minimize glare, eliminate dust gaps, and boost daytime visibility. The QUM upgrades Mercedes-Benz cabins with crisp QLED (1920×720) and EVO Bluetooth audio routing to eliminate sound delay.

Exclusive XTRONS UI & Live OTA Updates — Features XTRONS’ uniquely designed, elegant home interface built for effortless in-car navigation and control. System updates, UI enhancements, and feature tweaks can be delivered seamlessly over the air via real-time OTA upgrades.

Stable & Battery-Friendly — Powered by the T113 industrial chip with a low 5 mA standby current that protects vehicle batteries, plus rapid 1–2 second reverse camera trigger.

No-Cut Plug-and-Play Installation — 100% harness matching with no wire cutting required, fully retaining original steering wheel controls and OEM features.

Note: Our earlier Linux units covered universal, VW, Fiat, Jeep, and the BMW E60 8.8" systems. The QUB and QUM are the next step up, filling the gap for larger original factory displays.

QUB & QUM Series — Specifications & Fitment

While QUB and QUM target different vehicle brands, they share the same core Linux system. Here are their respective specifications::

QUB 12.3" Series — BMW Screen Replacement

The QUB series offers comprehensive coverage for BMW, ranging from 8.8" and 10.25" to the flagship 12.3" 2K QLED models. Built on the stable Linux architecture (Allwinner T113), the lineup provides a seamless plug-and-play upgrade across major BMW chassis.

QUM 10.25" Series — Mercedes-Benz Screen Replacement

The QUM series delivers a premium 10.25" QLED upgrade for Mercedes-Benz. Built on the stable Linux architecture (Allwinner T113), it offers seamless plug-and-play integration across major Mercedes chassis. For specific NTG/EVO models, it features Bluetooth audio routing to eliminate the traditional sound delay, ensuring a perfectly synced in-car experience.

*Note: Some specific models (e.g., GLK NTG 4.0, E-Class Coupe) are available in specific LHD or RHD configurations.

Need a larger screen? The 12.3" 2K QLED versions (SAM-QUM240/245/250) are available for special order. For specific SKUs and detailed LHD/RHD mapping, please contact our B2B team for the complete list.

Mercedes Audio Note: On specific Mercedes-Benz NTG platforms, audio is transmitted via Bluetooth rather than the traditional analog path — this removes the noticeable lag between screen action and sound that affects many aftermarket replacements.

XTRONS Brand Distinction: Quality, Packaging & Customisation

Automotive-Grade Build & Full Lamination: The QUB features a full lamination process that bonds screen layers together, providing brilliant optical transparency and extreme resistance to thermal expansion under temperatures from −20 °C to +75 °C.

XTRONS Exclusive UI: Engineered in-house, our custom-tailored user interface offers an intuitive layout that simplifies driving operations without complex menu diving.

Live OTA Upgrades: Keep units running with the latest firmware directly over the air without requiring manual card flashing.

Certifications & Testing: Fully CE, FCC, E-Mark (R10) certified, and RoHS compliant. Tested against high/low thermal cycles, 1.2 m drops, and vibration.

B2B Customisation: Supporting custom boot logos (no MOQ), custom homepage UI modifications (MOQ 500+), and tailored partner packaging.

Frequently Asked Questions

What is the difference between the QUB and the QUM?
The QUB is a 12.3" 2K QLED (2400×900) factory-screen replacement for BMW, in a CNC-cut metal body. The QUM is a 10.25" QLED (1920×720) factory-screen replacement for Mercedes-Benz, in a private-mold body, with Bluetooth audio routing on EVO models.

How fast does it boot?
Cold boot is about 3 seconds, hot boot about 1 second, and standby current is only 5 mA — the reverse camera activates in 1–2 seconds from standby.

Does it support wireless CarPlay and Android Auto?
Yes. Both QUB and QUM support wireless and wired CarPlay and Android Auto, plus iOS and Android screen mirroring.

Will installing it damage my car or lose factory functions?
No. Both are 100% plug-and-play — the harness matches the original connectors, no wires are cut, and steering-wheel controls and factory features are fully retained.

Does the QUM solve the Mercedes EVO audio-delay problem?
Yes. On EVO platforms, audio is transmitted over Bluetooth, removing the traditional lag between on-screen action and sound.

Can I install apps on the Linux system?
Not directly — by design. The closed Linux architecture keeps the unit stable and secure; you access your phone's latest apps, maps and music through CarPlay, Android Auto and screen mirroring.

Can the firmware be updated?
Yes. Both series support OTA upgrades for the latest UI, connectivity and improvements.

Is OEM/ODM customization available?
Yes — boot-logo branding (no MOQ), custom home UI and custom packaging (MOQ 500). Contact the XTRONS B2B team for details and the fitment list.
