4. Installation and Initial Setup
Professional Installation Advice:
While this unit features a plug-and-play design, due to the intricate electrical systems in Mercedes Benz vehicles, we strongly recommend installation by a qualified automotive electrician. This ensures all functions operate correctly and helps avoid potential risks or damage to your vehicle's electrical system.
Installation Steps:
- Prepare the Vehicle: Adjust the steering wheel to its lowest position.
- Remove Original Instrument: Use a pry tool to carefully remove the card/plate surrounding the original instrument. Unscrew the screws on both sides of the original instrument and gently remove it from the dashboard.
- Route USB Cable: Open the side card plate (usually near the driver's door or under the dashboard) with a tool. Insert the USB cable from the inside, ensuring it is placed in a good position for future upgrades or access.
- Transfer Components: Remove any iron pieces or clips from both sides of the original instrument and install them onto the new digital instrument cluster.
- Connect Cables: Install the USB, power, and data transmission cables to the new instrument cluster in the correct order. Ensure all connections are secure.
- Install New Instrument: Tilt the new instrument cluster into position. Press down on both side levers simultaneously to ease the meter in. Ensure the top and bottom mounting holes are aligned. Push the unit in firmly and tighten the screws.
- Synchronize Data: Connect the old instrument (if required for mileage transfer) with a data transmission cable. Hold down the [OK] key on the steering wheel to initiate data transmission and synchronization.
- Finalize Installation: Once data synchronization is complete and checked, carefully place all wires in their designated positions. Snap back any tabs or covers, and ensure all components are securely fastened.
Initial Configuration:
After installation, personalized settings such as language, units (e.g., km/h or mph, Celsius or Fahrenheit), and display themes can be easily adjusted via the steering wheel controls and the dashboard's built-in menu. Refer to the 'Operating' section for more details on theme switching.
