Technical Information

• Manufacturer: Stellantis
• Model: Citroën C4, Citroën C5, Citroën C8, Peugeot 308, Peugeot 807
• Product Codes: 9655613780, 6561Z9, 6561W5
• Other Numbers: 6561W5, 6561Z9, 9655613780 (common references)

Function and Compatibility

The antenna provides the vehicle with external radio reception and, depending on the vehicle equipment, may carry additional aerial feeds for telematic or navigation modules. Compatibility is determined by the antenna base and connector type; the listed OE codes are the fastest way to confirm a match for the vehicle.

Replacement Procedure

1. Park the vehicle on a level surface and isolate electrical loads where necessary. For safety, disable accessories as required by your workshop procedures.
2. Remove any interior trim or roof lining access panels covering the antenna base — typically located above the headliner near the roof centre or rear roof area, depending on model.
3. Unscrew the antenna mast or remove the antenna cover to access the mounting nut and the coaxial connector. Retain any sealing gaskets if reusable.
4. Disconnect the coaxial cable and any additional wiring harness from the antenna base. Inspect connectors and wiring for corrosion or damage.
5. Unscrew the mounting nut and remove the antenna assembly from the roof. Clean the mounting area and replace seals if necessary to maintain watertightness.
6. Fit the new antenna, reconnect cables, secure the mounting nut to the correct torque, and reinstall interior trim. Test radio reception and any dependent systems before returning the vehicle to service.

Installation Recommendations

• Use correct torque values for the mounting nut to ensure sealing and proper grounding of the antenna mast.
• Replace weather seals or gaskets to prevent water ingress; a compromised seal is a common source of failure.
• Check and, if necessary, clean coaxial connectors and earth points to avoid reception issues caused by poor connections or corrosion.
• When reinstalling headliner or trim, ensure wiring is routed without sharp bends or pinching to prevent future cable damage.
• After replacement, verify AM/FM reception across multiple stations and confirm any integrated systems (e.g., hands-free or navigation antennas) are functioning if applicable.

Most Common Failure Causes

• Mechanical damage to the mast or base from car washes, vandalism or impacts.
• Water ingress and corrosion at the base or connectors leading to poor continuity or short circuits.
• Worn or broken coaxial cable and connector fatigue from years of movement and vibration.
• Poor grounding or loose mounting causing intermittent reception or noise.

Searchable OE numbers 9655613780, 6561Z9 and 6561W5 help locate the correct antenna quickly. Suitable for professional garages and experienced DIYers familiar with roof trim removal and basic vehicle electrical checks.

This high-quality replacement antenna is designed for Citroën and Peugeot vehicles and matches common OEM references used by Stellantis. Ideal for professional workshops and DIY mechanics, the antenna restores reliable radio reception and fits as a direct replacement for the listed models. The part is often searched by its product codes, so finding the correct reference (9655613780 / 6561Z9 / 6561W5) speeds up procurement and installation.

Benefits include straightforward fitment, robust weather-resistant construction, and compatibility with factory mounts and cabling in the specified vehicles. The antenna restores AM/FM reception performance and integrates with vehicles that use an external aerial mast or roof-mounted antenna base. It is a practical spare part for routine repairs after mechanical damage or signal degradation.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C4, Citroën C5, Citroën C8, Peugeot 308, Peugeot 807
• Product Codes: 9655613780, 6561Z9, 6561W5
• Other Numbers: 6587J0

Installation Recommendations

Fitment is generally straightforward for experienced technicians. Typical installation steps:

• Park the vehicle on a level surface and disconnect the negative battery terminal to avoid short circuits while working on electrical components.
• Remove any interior trim or headliner sections required to access the antenna mounting nut from inside the roof or remove the external protection cap if applicable.
• Unscrew the retaining nut and carefully disconnect the antenna coaxial cable and any power plug for an integrated amplifier.
• Install the new antenna, ensure the sealing gasket is correctly positioned to prevent water ingress, reconnect the cable and any power connector, then torque the retaining nut to the manufacturer’s specification.
• Reassemble trim/headliner, reconnect the battery, and verify radio reception and any amplified reception function. Adjust seating to ensure watertight fit.

Why This Part Fails

• Mechanical Damage: Impact, theft attempts, or hammering during car washes can bend or break the mast or base.
• Corrosion and Water Ingress: Seals and connectors can corrode over time, degrading electrical contact and allowing water into the base.
• Cable Or Connector Faults: Damaged coaxial cable or corroded connectors reduce signal quality or interrupt antenna power for amplified systems.
• Amplifier Failure: Some antennas include a small amplifier; age or moisture can cause the amplifier to fail, resulting in poor reception.

Practical Tips

• Always Compare Product Codes: Match the codes printed on your old antenna with the numbers listed above to ensure correct fitment.
• Check Sealing During Reassembly: Proper sealing prevents future water-related failures.
• Inspect Coaxial Cable Condition: Replace or reseat damaged cables and connectors to restore optimum reception.

Order this antenna if your vehicle displays weak or intermittent radio reception, visible antenna damage, or if the mounting/base shows signs of corrosion. The referenced product codes (9655613780, 6561Z9, 6561W5) are commonly used identifiers for this part and will help you confirm fitment quickly.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C4, Citroën C5, Citroën C8, Peugeot 308 (and compatible models)
• Product Codes: 9655613780, 6561Z9
• Other Numbers: 6561Z9 | 9655613780

Function And Fitment Notes

The antenna unit provides radio signal reception for the vehicle’s audio system. Depending on the original equipment specification, the unit may be a simple passive antenna or include an integrated amplifier. Fitment must match the roof mounting and connector type of the vehicle—verify the OE code (9655613780 / 6561Z9) when searching. The part is intended as a direct replacement for the listed Citroën and Peugeot models; compatibility with other models may apply when the mounting and connector are identical.

Installation Recommendations

• Prepare Tools: Basic hand tools, trim removers, and a wrench or socket for the antenna retaining nut. If the mast is included, keep appropriate pliers for removal/installation.
• Access: Remove any interior roof trim or headliner access panels to reach the antenna retaining nut and cable connector. Protect upholstery and trim when lowering panels.
• Disconnect: Before disconnecting electrical connectors, ensure the ignition is off. It is good practice to isolate the battery if you will be working near electrical circuits or metal roof parts, to avoid short circuits.
• Removal: Unscrew the retaining nut securing the antenna from the roof. Carefully feed the cable through the roof aperture and disconnect the coax/antenna connector from the radio or amplifier module.
• Installation: Fit new gasket/seal (use a new seal where possible), feed the cable, connect the coax connector securely and fasten the retaining nut. Reinstall trim and test reception before final reassembly.
• Testing: Check AM/FM reception and any amplified functions. If reception is weak after replacement, inspect coax continuity, connector corrosion, and ground contact.

Why The Part Fails Most Often

• Mechanical Damage: Mast or external elements can be bent or snapped by car washes, low clearances, or impacts.
• Water Ingress And Corrosion: Seals degrade over time, allowing moisture into the antenna base or connector which causes corrosion and loss of contact.
• Connector Or Cable Failure: Coax connectors and cables can become corroded, crushed, or suffer broken cores that reduce signal quality.
• Amplifier Fault (If Present): Integrated amplifiers can fail electrically, causing poor or no reception even if the antenna mast appears intact.

Search Tips: Customers often find this part by entering OE numbers 9655613780 or 6561Z9. If the mast is missing or damaged, consider purchasing the antenna together with the mast for a complete replacement.
