Upgrading the interior of your 2015–2017 Mercedes-Benz C-Class (W205) can completely transform the driving experience — both in terms of aesthetics and functionality. If you’re looking to bring your cabin into the modern age with a sleek digital interface, touch controls, and the luxury feel of the 2020+ models, a full OEM retrofit is the answer.

At CryptoAutoParts.ae, we specialize in genuine Mercedes-Benz retrofits and offer a complete, ready-to-install solution to upgrade your vehicle’s interior — using 100% brand-new OEM parts.

🚗 Why Upgrade Your W205 Interior?

Owners of pre-facelift C-Class models (2015–2017) often notice how much the newer interiors feel more advanced, cleaner, and high-tech. The 2020+ facelift introduced:

High-resolution touchscreens
Digital instrument clusters
Sleek steering wheels with touch-sensitive controls
A more refined and modern infotainment system (NTG5.5/MBUX-compatible)

If you’re passionate about your Mercedes and want to keep it up-to-date, an interior retrofit is one of the smartest and most rewarding upgrades.

🔧 What’s Included in the W205/W253 Retrofit Kit?

Our Mercedes-Benz W205 / W253 OEM Full Retrofit Kit includes everything needed to transform your cabin to 2020+ specs:

📦 Complete OEM Components:

🖥️ Touch Display: Large, high-resolution central screen — facelift-style
🎛️ Digital Instrument Cluster: Fully digital, customizable, modern interface
💿 NTG5.5 Head Unit: Latest-generation infotainment system with fast performance, media integration, and navigation support
🛞 2020 Steering Wheel: Leather Alcantara multifunction steering wheel with paddle shifters and touch buttons
🔌 USB Hub: Ensures full connectivity for CarPlay, Android Auto, and fast charging
⚡ IC Adaptor: For proper communication between cluster and head unit
🧠 Steering Switch Retrofit Adaptor: Ensures full compatibility with factory systems and electronic controls

Every component is brand new, factory-original, and designed to work flawlessly together for a plug & play experience (some coding required).

🛠 How Does the Retrofit Work?

1. Disassembly and Preparation

Your technician will first remove the existing head unit, cluster, steering wheel, and trim pieces. Battery should be disconnected to ensure safety during electrical work.

2. Installation of New Components

Each OEM part is mounted directly into the vehicle using the same factory fittings and brackets. The NTG5.5 head unit and display are mounted with appropriate LVDS and power lines.

3. Wiring and Adaptors

The kit includes all necessary adaptors to bridge communication between the old chassis (2015–2017) and new-generation components. No cutting or splicing required.

4. Online Coding and CP Removal

Component Protection (CP) must be removed using official tools like XENTRY, Vediamo, or DTS Monaco. Final VIN adaptation and SCN coding ensure full integration of the head unit, cluster, and steering wheel controls.

5. Testing and Activation

Once installed, systems like media, navigation, cluster animation, steering input, and USB ports are tested. All features must function like a factory-fitted 2020+ interior.
