Vehicle Compatibility

This display may be suitable for selected Mercedes-Benz C-Class W204 sedan, S204 wagon and C204 coupe vehicles equipped with a compatible factory COMAND navigation system.

Compatibility depends on the vehicle production date, installed NTG generation, display mechanism, electrical connector, hardware number and factory infotainment equipment.

Please compare part number A1729012900, all associated numbers, the connector, mounting points and display assembly with the original unit before purchasing.

Mercedes-Benz vehicles with Audio 20, Becker Map Pilot or another infotainment configuration may use a different screen. Similar-looking displays should not be considered interchangeable solely because they fit the same dashboard location.

Coding and Programming Requirements

Coding, programming and component-protection removal are not normally required when installing this display as an exact like-for-like replacement in a compatible factory COMAND system.

The display functions as the visual monitor for the separate COMAND infotainment computer. A diagnostic scan and stored fault-code clearing may still be recommended after installation.

Coding or vehicle-specific configuration may be required if the COMAND main unit is also replaced, the vehicle is being converted from another infotainment system or the replacement display does not match the original system generation.

Installation Information

Professional installation by a Mercedes-Benz technician or experienced automotive infotainment specialist is recommended.

The vehicle should be diagnosed before replacement to confirm that the display is responsible for the fault. The COMAND main unit, wiring, connectors, power supply and screen mechanism should also be inspected.

The dashboard trim and display assembly should be removed carefully to avoid damaging the surrounding interior panels, wiring or motorised mechanism where equipped.

After installation, the screen image, navigation display, radio information, multimedia menus and opening or closing operation should be tested where applicable.
