• consistency with factory software and multimedia system operation logic,
• proper cooperation with existing control modules in the vehicle,
• preservation of the original cockpit appearance and ergonomics,
• stable operation within the vehicle's electrical installation.

Thanks to this, replacing a damaged screen with an original component allows for restoring full functionality of the navigation and radio system without the need for installation modifications or the use of adapters.

Characteristics of the used component

When selecting a display for a specific Mercedes S-Class unit, it is worth using vehicle data and factory markings to ensure full hardware and software compatibility.
