🔧 Mercedes-Benz E-Class Interior Retrofit (W213/W238 2017–2020 ➝ 2021 KIT5)
Full OEM Upgrade to 2021 Digital Cockpit — NTG 6, MBX, and Touch Control
As a Mercedes-Benz retrofit engineer specializing in E-Class and S-Class digital upgrades, I’ve led numerous OEM retrofit projects upgrading 2017–2020 E-Class (W213/W238/C238) interiors to the facelift 2021+ model. This retrofit gives your vehicle the full digital transformation found in the 2021 E-Class: MBUX interface, NTG6 platform, touch display, digital cluster, and new-generation steering wheel.
📦 Included in KIT5 – OEM Retrofit Components:
Touch Display (Central Media Screen)
Fully capacitive touchscreen (2021 facelift spec).
Integrated into dashboard with genuine Mercedes frame.
High-resolution display, paired with NTG6.
NTG 6 Head Unit (MBUX MID Version)
The heart of MBUX: faster, smarter infotainment system.
Supports online navigation, voice control, touch, and gestures.
Includes native Apple CarPlay/Android Auto.
Instrument Cluster (Digital Widescreen Unit)
12.3” digital display replacing analog/hybrid gauges.
Animated transitions, drive mode graphics, and customization.
Communicates with MBUX via LVDS and CAN protocols.
2021 Steering Wheel (Touch Control Buttons)
Redesigned multi-function steering wheel with capacitive controls.
Supports scroll, swipe, and touch gestures.
Requires retrofit adapter for compatibility with 2017 SCU.
Touchpad Controller (Mouse Unit)
Replaces rotary COMAND controller.
Controls NTG6 via gestures and pressure feedback.
Mounts directly in center console with minor fascia trimming.
USB Media Interface (Fast-Charge & CarPlay Port)
High-speed dual USB-C ports.
Required for CarPlay/Android Auto functionality.
Mounts in original console slot.
MBX Adapter (CAN Gateway for Retrofit)
Bridges compatibility between old CAN/LIN networks and new MBUX modules.
Ensures cluster and HU work with legacy chassis (2017–2019).
Includes CAN conversion, LIN signal adaptation, and ignition sync.
⚙️ Technical Installation & Programming Steps
Step 1: Disassembly & Preparation
Disconnect battery (safety first).
Remove OEM head unit, cluster, display, center console, and steering wheel.
Backup all original coding via XENTRY, Vediamo, or DTS Monaco.
Step 2: Hardware Installation
Install touch display into dash using facelift bracket/frame.
Mount NTG6 MID head unit behind dash and connect LVDS, CAN, USB, GPS, and power.
Fit digital cluster and plug in CAN+LVDS lines via MBX adaptor.
Replace steering wheel; use W213 steering retrofit adapter for SCU compatibility.
Install USB ports and mouse touchpad in original slots.
Step 3: MBX Adapter Integration
Connect adapter between CAN backbone and cluster/HU lines.
Ensure proper pin-to-pin mapping with factory wiring.
Sync ignition voltage triggers for coordinated boot-up.
Step 4: Coding & Activation
Launch XENTRY Diagnosis or DTS Monaco.
Code NTG6 and cluster with correct VIN & variant coding.
Perform SCN coding or offline flashing (MBUX requires online account or dealer access).
Activate features: Touch control, voice commands, display layout, and dynamic animations.
Step 5: Final Testing & Calibration
Test screen responsiveness, touchpad function, and steering controls.
Confirm all media, navigation, and voice features.
Verify cluster animations, drive mode switching, and warning messages.
✅ Final Outcome: What You Gain
✔ Sleek 2021-style digital dashboard with MBUX✔ Full touchscreen interface and smart voice assistant✔ Modernized steering wheel with touch inputs✔ Faster infotainment system with enhanced graphics✔ Wireless Apple CarPlay & Android Auto✔ Factory look, feel, and function — indistinguishable from original 2021 E-Class
