Description
Car radio with CD/MP3, Navigation and GSM — RT3-N3-10. The radio must be coded/paired to the vehicle using diagnostic equipment. It originates from a Peugeot 407 (2005).
This RT3-N3 multimedia unit (CD/MP3 player with integrated navigation and GSM module) is a direct-fit radio taken from a Peugeot 407 and is sought under codes such as 96601833YW. Designed for technicians and experienced DIYers, the unit brings factory-style navigation, hands-free mobile connectivity and CD playback in one module. Its OEM fitment preserves dash aesthetics and vehicle wiring without major modifications.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: RT3-N3 Radio Unit — From Peugeot 407 (2005)
- Product Codes: 96601833YW
- Other Numbers: 657477, 657478, RT3-N3-10
Function and Benefits
The unit provides in-dash navigation, CD/MP3 playback, radio reception and GSM connectivity for hands-free calls (function availability depends on vehicle configuration). Using the original RT3 platform ensures compatibility with steering-wheel controls, vehicle CAN-bus messages and factory amplifier systems when correctly coded to the car.
How It Is Replaced
- Disconnect Vehicle Battery: For safety and to avoid electronic faults, disconnect the negative battery terminal before starting.
- Remove Trim And Fascia: Carefully remove the surrounding trim panels using appropriate plastic trim tools to avoid damage.
- Unscrew And Extract Radio: Remove mounting screws and slide the radio from the dash. Unplug antenna, speaker loom, power connector and any GPS/GSM antenna leads.
- Install And Reconnect: Fit the replacement unit, reconnect all harnesses and antennas, then resecure the unit and refit trim panels.
- Diagnostic Coding: After mechanical installation, the radio must be coded/programmed to the vehicle using a compatible diagnostic tool so that all functions (immobiliser-linked features, Bluetooth, navigation and amplifier control) operate correctly.
Installation Recommendations
Use appropriate dash removal tools to avoid breaking clips. Keep connectors and antenna plugs clean and corrosion-free. When reconnecting the battery, allow a few minutes for vehicle electronics to initialise. Perform the coding step with a manufacturer-level diagnostic interface or a specialist workshop familiar with RT3-N3 series units.
Why This Part Commonly Fails
Common failure causes for RT3-N3 units include connector corrosion (often from moisture ingress behind the dash), worn CD mechanism, failed internal capacitors or power supply components due to age and heat, and software/hardware faults in the GSM or navigation modules. Repeated thermal cycling and vibration in older cars (typical for a 2005 vehicle) increase the likelihood of electrical faults.
Expected Lifespan And Reliability
With proper installation and a dry environment, factory multimedia units can last many years. However, units from early 2000s vehicles often show increased failures after a decade due to mechanical wear of moving parts (CD drive) and aging electronic components.
Notes
Unit Codes Such As 96601833YW And The RT3-N3-10 Identifier Are Useful For Matching Compatibility. Because The Unit Requires Diagnostic Coding To The Car, Plan The Coding Step Into The Replacement Procedure.
