Description
Radio display NAVIGATION heating PEUGEOT 407 facelift also possible on Citroen C5 X7
During installation, it is necessary to play with the car software
It is from a PEUGEOT 407 2008
Part description
This navigation / radio and heater control display is intended for PSA cars and is primarily searched for by part numbers. It is a used original part from the on-board infotainment system, which ensures the display of information and the operation of functions according to the vehicle’s equipment. Suitable when replacing a non-functioning display (dropouts, poor readability, unresponsive display) or when there is a communication failure of the units in the on-board network.
With this type of display, it is important to take into account that software pairing/matching with the car may be required after installation, as indicated in the documents.

Installation recommendations
Generally/typically, replacing the display (electronic part of the dashboard) may vary depending on the specific equipment and design of the car. It is explicitly stated in the documents that after installation, the part must be played with the car in software.
1) Before assembly (checks)
- Compare the part numbers on the label: 9673538880, 659371, 6593Q4 with the old part.
- Check the connectors (broken locks, bent pins), the condition of the front glass of the display and any cracks.
- If the original part was defective, verify that the problem was not caused by wiring or a loose connector.
2) Necessary tools and materials (in general)
- A set of common hand tools (screwdrivers, bits)
- Plastic pry bar for panel removal (to minimize plastic damage)
- A clean cloth and possibly a contact cleaner (depending on the condition of the connectors)
- Diagnostics for PSA (for subsequent software matching with the car)
3) Step-by-step assembly procedure (typically)
- Turn off the ignition and wait for the car’s systems to sleep.
- Disconnect the battery (recommended for electronic parts of the on-board network).
- Remove the bezels/trimming around the display unit (use a plastic pry bar).
- Unfasten the display and carefully slide the unit out so that the connectors can be safely disconnected.
- Disconnect the electrical connectors – do not pull the cables, but the connector body/lock.
- Connect the connectors to the new (used) display and check that the locks are properly seated and secure.
- Place the display back in place and secure it.
- Refit the removed trim/covers.
- Connect the battery.
- Turn on the ignition and verify that the display starts up and communicates with the car’s system.
- Perform software matching/pairing with the car according to the possibilities of diagnostics and vehicle equipment (indicated as necessary in the documents).
-
4) Post-assembly checks and test verification
- Check functionality of display and control responses.
- Verify that there are no dropouts (flickering, black screen) during normal operation.
- After playing the software, verify the basic functions of the system according to the car’s equipment.
5) The most common assembly mistakes + how to avoid them
- Loose connector → always check locks and secure snaps.
- Plastic damage during disassembly → use a plastic pry bar and proceed patiently.
- Omission of software compatibility → consider the need for diagnostics after installation (listed in the documents).
- Handling under voltage → with electronics, it is safer to disconnect the battery before disconnecting the connectors.
Reasons why the part is damaged
- Electronic aging and temperature stress in the interior (heat/cold) leading to display failures.
- Faulty or loose connectors, transition resistors and power fluctuations.
- Mechanical damage during unprofessional disassembly (cracks, damaged connector locks).
- Moisture and oxidation of contacts, which can cause unstable operation or complete failure.
