Compatibility
Works as a direct replacement on vehicles listed above where the original part number matches. Customers frequently search using the OEM numbers 9650911780 and 6561HG to find the correct antenna socket for their Citroën C3 and C5.
Function And Typical Symptoms
The antenna socket provides the physical and electrical interface between the vehicle’s external antenna and the radio/navigation head unit. When this socket degrades or fails, typical symptoms include intermittent or weak radio reception, loss of certain radio bands (AM/FM/DAB), static or noise on the audio band, or disrupted navigation signal quality. In some cases a poor connection may present as a loose or wobbly antenna base.
Why The Part Most Often Fails
Common failure causes include corrosion from water ingress, mechanical wear or damage caused by impact or improper handling during previous repairs, and connector pin deformation from repeated disconnects. Environmental exposure (road salt, moisture) accelerates corrosion, while incorrect mounting or overtightening can cause mechanical failure.
Replacement Procedure
- Prepare the vehicle: Park on level ground, engage the parking brake and disconnect the negative battery terminal to avoid electrical shorts during work.
- Access the socket: Depending on model, access may require removal of interior trim, headliner sections or the radio/navigation unit to reach the antenna socket connector.
- Disconnect: Carefully unplug the antenna socket connector from the head unit or wiring harness. Inspect the mating connector and cable for corrosion or damage.
- Remove and fit: Unscrew or unclip the old socket and install the new one in the reverse order. Ensure correct alignment of pins and secure mechanical fastenings without over-torquing.
- Test: Reconnect the battery, power up the radio/navigation and verify reception across bands and navigation signal stability before reassembling trim.
Installation Recommendations
- Use plastic trim tools to avoid damaging interior panels.
- Inspect the antenna cable and mating connector for corrosion; replace damaged cables to ensure long-term reliability.
- Apply a dielectric grease to connector contacts if exposed to moisture-prone environments to reduce future corrosion risk.
- When reassembling, make sure the socket is seated properly and cable routing avoids sharp edges or pinch points.
Notes For Professionals
Part numbers 9650911780 and 6561HG are commonly used in workshop searches and should be verified against the vehicle’s parts catalog when performing large repair jobs. This socket is suitable for use by trained technicians and competent DIYers experienced with vehicle electrical systems.
