• stable operation of the navigation and multimedia system,
• preservation of the original user interface,
• consistent fitment within the dashboard.

As an item from the Electronic control modules and controllers group, the screen is prepared for compatibility with factory wiring harnesses and connectors, which reduces the risk of compatibility issues.

Condition, verification, and preparation for installation

The product comes from disassembly and is offered as a used original component, which in practice means a beneficial combination of OEM quality and an attractive purchase cost. Before being offered for sale, the module is verified for correct image performance and response to signals from the control system to ensure functionality as intended.

During installation, it is recommended that the work be performed by a workshop experienced with Mercedes electronics, which facilitates proper connection, potential adaptation, and post-installation testing. Proper seating of the screen in the center console helps avoid mechanical stress and ensures long-term, stable operation.
