Description
Antenna socket for radio and navigation for Citroën C3, Citroën C5.
This antenna socket is an OEM-style replacement part designed for the radio and navigation systems used on Citroën C3 and Citroën C5 vehicles. Frequently searched by product codes 9650911780 and 6561HG, the part restores the mechanical and electrical connection between the vehicle antenna and the coaxial lead, improving reception for AM/FM radio and GPS/navigation antennas. Designed for professional workshops and competent DIYers, this component is a straightforward, cost-effective repair to eliminate weak reception, intermittent signal loss, or a completely dead antenna feed.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C3; Citroën C5
- Product Codes: 9650911780; 6561HG
- Other Numbers: No Additional OEM Numbers Listed
Function And Symptoms
The socket provides the physical mount and electrical contact for the antenna lead. When the socket degrades or fails, common symptoms include poor AM/FM reception, intermittent audio artifacts, weak radio stations, loss of GPS/navigation signal, or complete absence of antenna continuity when measured with a multimeter. Checking these symptoms alongside the product code helps to quickly identify the correct replacement.
Installation Recommendations
- Preparation: Work in a dry, clean area. Disconnect the negative battery terminal if major trim or roof panel removal is required to avoid short circuits.
- Access: Remove interior trim or headliner sections as required to reach the antenna base (roof or rear glass area depending on vehicle). Keep fasteners organized for reassembly.
- Removal: Disconnect the antenna coaxial connector from the socket, unfasten mounting hardware, and remove the old socket carefully to avoid damaging the coax cable or surrounding seals.
- Installation: Fit the new socket, ensuring the mating surfaces and gaskets are clean and undamaged. Reconnect the coaxial connector firmly and secure the mounting hardware according to manufacturer recommendations. Use a new sealing gasket or appropriate sealant to prevent water ingress if the original shows wear.
- Post-Installation Check: Verify radio and navigation reception, inspect for water tightness around the mount, and ensure all trim and fasteners are refitted correctly.
Common Failure Causes
Failures usually result from long-term exposure to moisture leading to corrosion of contact surfaces, mechanical damage from impacts or improper antenna removal, degradation of plastic parts and gaskets due to UV and temperature cycles, or wear of the internal contact that interrupts the signal path. Environmental exposure in coastal or salted-road regions accelerates corrosion and shortens service life.
For mechanics and DIYers replacing this part: verify the product codes (9650911780, 6561HG) match the vehicle application, inspect the coax cable and connector for damage, replace any brittle or corroded gaskets, and retest reception after installation to confirm the repair.
