Description
Radio and onboard computer display for PEUGEOT 407. Some functions may need to be activated using diagnostic equipment.
High-quality replacement display for Peugeot 407 vehicles designed for mechanics and DIY enthusiasts who need a reliable central information unit for radio and trip-computer functions. The unit is a common aftermarket/used spare that fits vehicles equipped with the factory central display. It is frequently searched by part numbers (9665118480, 659349), so technicians and independent workshops can quickly locate the correct unit for repair or refurbishment projects.
This display shows radio information, clock and time, onboard computer readouts (trip, range, average fuel consumption), and system notifications. It helps restore full visibility of infotainment and driver information when the original screen has failed, become dim, or shows pixel defects. Some features, such as certain radio or vehicle-specific functions, may require activation or coding with diagnostic equipment after installation.
How To Replace
General replacement steps for experienced technicians or confident DIYers:
- Disconnect the negative battery terminal before starting to prevent short circuits and protect vehicle electronics.
- Remove surrounding trim panels carefully using appropriate plastic trim tools to avoid damage to the dash finish.
- Unscrew the display retaining screws and gently pull the unit forward to access the rear connectors.
- Unplug the electrical connectors and any antenna or ribbon cables—note connector orientation and locking clips.
- Install the new display by reversing removal steps: reconnect all plugs, secure the unit, refit trim, and reconnect the battery.
- After fitment, verify all functions. Some features may require coding or activation via a diagnostic tool.

Reason Why The Part Most Commonly Fails
- Backlight or LCD degradation over time causing dimming, uneven illumination, or dead pixels.
- Thermal stress and aging of electronic components or solder joints, leading to intermittent or permanent failure.
- Moisture ingress or connector corrosion causing loss of signal or display artifacts.
- Mechanical damage during removal/installation or from dashboard impacts.
- Power supply issues from vehicle wiring (voltage spikes, poor grounding) accelerating failure of the display electronics.
