Description
Antenna impedance module, impedance adapter for PEUGEOT 307 CC cars
Part description
This antenna module (impedance adapter) is used to adjust the impedance in the car’s antenna system to ensure proper signal transmission to the car radio. It is suitable as a spare part in case of malfunctions in the radio reception or when replacing the car radio and accessories, where it is necessary to maintain the correct connection and function of the antenna.
In practice, this type of part is often searched for by product numbers 9652016980 and 6561R5 – thanks to this you can easily compare the match with the existing part in the car.

Installation recommendations
Generally/typically for antenna modules and impedance adapters in the car radio/antenna line, the exact design and placement may vary depending on the equipment and wiring of the car. Consider the procedure below as a practical guide for this type of part.
1) Before assembly
- Compare the old and new piece: codes 9652016980 / 6561R5, connector shape, number and type of inputs/outputs, mounting method.
- Check the condition of the connectors (bent pins, oxidation) and wiring (damaged insulation, breaks).
- If the problem was weak/fluctuating reception, also check the antenna cable and connection to the chassis (typically the source of the fault).
2) Necessary tools and materials
- Basic set of screwdrivers and ratchets (depending on the design of the interior covers)
- Plastic pry bar for removing the paneling (so as not to damage the plastics)
- Electrical contact cleaner (for connectors)
- Dry cloth, possibly insulating tape/tapes for fixing the cabling
3) Step-by-step assembly procedure
- Turn off the ignition and, for safety, disconnect the battery (typically the negative pole).
- Get access to the part – dismantle the necessary covers/paneling around the car radio or antenna line (depending on the specific design).
- Take a photo of the original connection of the connectors to avoid confusion during reassembly.
- Disconnect the connectors from the old antenna module (do not pull on the cables; release the connector fuses if present).
- Check the connectors and, if necessary, gently clean them with contact cleaner and let them air out.
- Remove the old module from the mounting (snap/screw – depending on the version).
- Install the new module in the holder so that the wiring is not stretched and does not bend at sharp bends.
- Connect the connectors in the same order as the original piece; check that the connectors are fully seated and the fuses are secured.
- Organize the wiring and secure it so it doesn’t rattle or rub against edges.
- Reinstall the removed covers/trims.
- Connect the battery.
-
4) Post-assembly checks and test drive/function verification
- Verify radio functionality: test reception of multiple stations and signal stability.
- Check for crackling/noise when driving (may indicate bad contact or loose connector).
- After a short ride, check again that everything is securely fastened and that nothing is loose.
5) The most common assembly mistakes + how to avoid them
- Switched or not clicked connectors → take photos of the original condition, always physically check the seat after connection.
- Pulling on cables when disconnecting → always release the connector by the body, not the wires.
- Oxidation of contacts → clean before assembly, deal with damaged pins before connecting.
- Bad cabling (breaks, pinching of the cover) → route the cables freely, without sharp edges and pressure.
Reasons why the part is damaged
- Moisture and oxidation in the connectors or at the installation site – leads to contact deterioration and signal dropouts.
- Mechanical damage to the wiring (pinched, broken, pulled) when disassembling the interior or the radio.
- Unprofessional intervention in the audio system – unsuitable adapters/connections can cause malfunction or unstable reception.
- Aging of materials and wear of connectors (loosening, loss of contact pressure).
