Installation Recommendations
- Always disconnect the vehicle battery before starting removal or installation to avoid short circuits and protect the vehicle electronics.
- Remove surrounding trim panels carefully using plastic trim tools to avoid damage. Unscrew the radio mounting bolts and slide the unit out slowly.
- Unplug the main harness, antenna lead and any amplifier/aux connectors. Inspect connectors for corrosion or broken pins and clean if necessary before connecting the replacement unit.
- Fit the radio into the dash, reconnect all plugs and the antenna, then refit mounting screws and trim.
- After mechanical installation, the radio must be programmed/coded to the vehicle using PSA diagnostic equipment (DiagBox/Lexia/PP2000 or equivalent). Without coding, some features (immobiliser-related functions, steering wheel controls, or CAN bus communication) may not work correctly.
- If the vehicle has an external amplifier, a CAN-bus interface or retained steering wheel controls, an adapter may be required to preserve these functions.
Why This Part Commonly Fails
- Mechanical wear Of The CD Mechanism: Moving parts (tray, laser assembly) degrade over years, causing read errors or refusal to load discs.
- Age-Related Electronic Faults: Electrolytic capacitors and solder joints can fail after long service, producing intermittent power loss or audio dropouts.
- Software/Memory Corruption: Stored settings or firmware issues may require reinitialization or reprogramming.
- Moisture, Dirt And Connector Corrosion: Water ingress or corroded plugs leads to poor contacts and malfunction.
- Physical Damage: Impact, improper removal or incorrect wiring can damage the unit or connectors.
Compatibility And Practical Notes

Use the listed product codes (9660646477, 96606464XT, 1614201480, 6564X9) when searching or ordering to improve match accuracy. Professional diagnostic coding is recommended to fully reinstate all functions after installation. For workshops: verify speaker wiring and amplifier presence before powering up the unit to avoid short circuits.
