🔧 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:

  1. Touch Display (Central Media Screen)

    • Fully capacitive touchscreen (2021 facelift spec).

    • Integrated into dashboard with genuine Mercedes frame.

    • High-resolution display, paired with NTG6.

  2. 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.

  3. 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.

  4. 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.

  5. Touchpad Controller (Mouse Unit)

    • Replaces rotary COMAND controller.

    • Controls NTG6 via gestures and pressure feedback.

    • Mounts directly in center console with minor fascia trimming.

  6. USB Media Interface (Fast-Charge & CarPlay Port)

    • High-speed dual USB-C ports.

    • Required for CarPlay/Android Auto functionality.

    • Mounts in original console slot.

  7. 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
