The Siemens VDO RD3-01 (often referred to by its PSA part numbers like 96476992ZE or 6564LY) is a staple head unit found in many Peugeot (206, 307) and Citroën (C3, C5) vehicles from the early-to-mid 2000s. While a single, unified "service manual" can be difficult to find in one PDF, the technical community has documented the pinouts, internal disassembly, and common repairs extensively. 1. Technical Specifications
The RD3-01 is a Phase-locked loop (PLL) radio with an integrated CD player. Power Output: 40 W (max). Frequency Bands: AM, FM (UHF), and Long Wave.
Integration: Connects to the vehicle’s VAN-bus for steering wheel controls and multi-function display integration.
Compatibility: Shared platform with Clarion (model PU-2471A or PU-2859A) and Blaupunkt units. 2. Connector Pinout & Wiring Diagram

Removal: Insert four removal tools or thin screwdrivers into the circular holes at the corners of the fascia to release the retaining clips.
Top Cover: Carefully pry the top metal plate with a flathead screwdriver to access the CD mechanism.
CD Reader: Remove the four screws securing the CD drive. Be mindful of the ribbon cables underneath. Adding an AUX Input Peugeot RD3-1 Radio Pinout Diagram | PDF - Scribd

You do not need a $5,000 Lexia 3 diagnostic tool to read basic errors on the RD3 01. The full service manual reveals the "secret button combination" to enter diagnostic mode:
The display will cycle through "Error Log." The manual decodes these cryptic messages:

The Siemens VDO RD3-01 (often identified as model ) is a standard head unit found in older Peugeot and Citroën vehicles. Because a single official "full" service manual is rarely available to the public, technical details must be compiled from repair databases and pinout guides. 1. Technical Architecture & Components
Main Chipset: Utilizes a SAA7708H DSP (Digital Signal Processor) chip. Memory (EEPROM): Contains a 24C32 EEPROM (4096 bytes).
Data Stored: Radio station presets and the vehicle’s VIN (Vehicle Identification Number).
VIN Location: Found in plaintext at the end of the EEPROM (offsets 0xFEF to 0xFFF). Modifying this allows the radio to be swapped into a different vehicle without "beeping". The Siemens VDO RD3-01 (often referred to by
Audio Routing: The CD drive is connected via SPDIF1, while the CD changer uses CD_RI and CD_LI inputs on the DSP. 2. Rear Connector Pinout (ISO 10487)

These are located above the main ISO blocks and are used for external modules.
Blue Connector (C13–C20): Dedicated to the External Multi-Disc CD Changer. Includes audio line inputs and VAN data bus connections.
Green Connector (C7–C12): Used for Auxiliary Line-In (often labeled "Line In from NAV") and mobile phone audio.
Yellow Connector (C1–C6): Generally used for remote display and steering wheel control interfaces. 4. Known Issues & Troubleshooting
AUX Circuit Design Error: There is a factory defect where the electrolytic capacitor for the IN- input of the TDA8579 line receiver is installed with reversed polarity. If you use the AUX input, this capacitor should be re-soldered with the positive side toward the TDA chip to prevent audio degradation.
Aux "Hack" Problems: Common DIY aux-in hacks that insert signals directly between the DSP and the amplifier chip are risky. They often require muting the radio to hear the aux source, and the competing signals between the external device and the DSP can damage the hardware.
Activation: If adding a CD changer or digital emulator (like Yatour), the option must often be enabled in the car’s BSI (Built-in Systems Interface) using diagnostic software. 5. Physical Service Steps Remove metal sleeve (if any) from radio chassis
Removal: Requires inserting four thin tools (or screwdrivers) into the side slots to release the spring clips.
Fuses: Some models feature a 10A blade fuse on the rear, though it may be absent depending on the specific production year. Siemens VDO RD3-01 Car Radio - Repair Wiki
The Siemens VDO RD3-01 is a standard factory head unit primarily found in PSA Group vehicles like the Peugeot 206, 307, and Citroën C3. While a single official "full service manual" is often difficult to find in one piece, the technical specifications, wiring pinouts, and common maintenance procedures are well-documented across several technical repositories.
