Description
Radio and trip computer display for Peugeot 308 T7. Some functions may need to be enabled via diagnostic.
This replacement display is designed for technicians and DIY enthusiasts who need a direct-fit unit for the Peugeot 308 (T7) dashboard. It restores full visual feedback for the radio, menu navigation and onboard computer readouts. Commonly searched by part numbers 9678491880, 9678491880-01 and 9821851780, this unit is suitable for vehicles originally equipped with the corresponding factory display module. The compact design and OE-compatible connectors make it an efficient repair option when the original screen shows dead pixels, backlight failure or intermittent communication with the head unit.

Compatibility
Fits Peugeot 308 models from the T7 series equipped with the factory radio/driver information display that uses the above part numbers. Ensure the connector type and bezel dimensions match the vehicle before installation.
What The Part Does
The display provides visual information from the radio, media system and onboard trip computer: station and track info, vehicle messages, fuel consumption, range and menu navigation. It acts as the primary interface for driver information related to audio and basic vehicle status.
Common Faults And Causes
- Backlight Failure: Aging LEDs or power-supply components cause dim or non-illuminated screens.
- Pixel Or Segment Loss: Internal panel degradation or impact damage can produce dead pixels or missing segments.
- Connector Or Ribbon Cable Issues: Oxidation, poor seating or broken flex cables interrupt the signal between the display and head unit.
- Software/Communication Errors: Intermittent messages or blank screens can result from module communication faults that sometimes require diagnostic intervention to restore full functionality.
- Environmental Damage: Heat, moisture or direct liquid ingress accelerates failure of electronic components and solder joints.
Installation Recommendations
Follow these steps to replace the display safely and reliably:
- Always disconnect the battery before starting work to avoid short circuits and protect vehicle electronics.
- Remove the trim panels around the radio carefully using plastic pry tools to avoid breaking clips or scratching surfaces.
- Unscrew the radio/display assembly and slide it forward enough to access the rear connectors.
- Unplug all connectors and carefully release any locking tabs on ribbon cables; inspect connectors for corrosion or bent pins and clean if necessary.
- Install the replacement display, reconnect all plugs and ribbon cables, then test all functions before reassembling the trim.
- If certain functions do not appear or menus are missing, a diagnostic tool may be required to enable features or reinitialise communication between modules.
- After installation, confirm radio, trip computer and dashboard messages operate correctly and that there are no stored fault codes related to the display.
Why This Part Commonly Fails
Displays are exposed to constant temperature cycles, vibration and usage. Over time the backlight, connectors or internal electronics wear out. Poor electrical supply, water ingress from a leak or mechanical damage during previous repairs are frequent root causes. In some cases, the display appears to fail due to communication errors with the head unit rather than a fully defective panel.
Notes For Technicians
Keep part numbers 9678491880, 9678491880-01 and 9821851780 handy when searching catalogues or cross-referencing stock. When replacing a display, verify connector layout and physical dimensions to ensure a correct fit. If activation of specific functions is required, plan for diagnostic time to enable those features.
