Part description

Used Blaupunkt RD4 T5 N2 car radio for cars of the Stellantis group (Citroën/Peugeot). It is an original OEM radio with a CD, which is often searched for by serial numbers – that is why it is an ideal choice when replacing a non-functioning unit or when dealing with audio dropouts, CD not reading or other defects of the original radio.

Important: the unit needs to be loaded/adapted to the car by diagnostics after assembly. The radio has 2 antenna inputs – before assembly, check the compatibility of the connectors and design with the original piece.

Installation recommendations

Generally/typically for this type of car radio: compare the connectors before installation, and after installation, the radio must be “uploaded” (paired/configured) to the car by diagnostics, otherwise it may not work properly. The exact steps may vary depending on the specific car model.

1) Before assembly

• Check the nameplate and compare the codes 9660646577 / 6564QT (or 6564QV, 6579PS) with the old radio.
• Check the design compatibility: Blaupunkt RD4 T5 N2, radio with CD.
• Compare connectors and accessories: power/speaker harness and 2 antenna inputs (type and number).
• Visually check the condition: connector damage, bent pins, cracks, traces of moisture.

2) Necessary tools and materials

• Basic set of hand tools (screwdrivers/ratchets according to dashboard design)
• Preparations for dismantling the radio (if required by the specific design)
• Clean cloth or contact cleaner (for connectors)
• Diagnostics for uploading/adapting the radio to the car (according to service equipment)

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery (to minimize the risk of short circuits and errors in the electronics).
2. Remove the surrounding dashboard covers to gain access to the radio (the procedure varies by car).
3. Unfasten and remove the original car radio.
4. Disconnect all connectors – power/speakers and antennas; note their position.
5. Compare the new (used) radio with the old one: connectors, mounts, label codes.
6. Plug the power/speaker connector and both antenna inputs into the new radio.
7. Insert the radio into the hole and secure it in place (without force, so as not to damage the connectors).
8. Reinstall the removed covers and frames.
9. Connect the battery.
10. Perform recording/adaptation of the radio to the car by diagnostics (according to the equipment and procedure for the given car).
• 4) Post-assembly checks and functional test verification
  • Verify radio power on, control function and backlight.
  • Check reception on both antenna branches (if the car uses them) and signal quality.
  • Test the CD drive (on clean, undamaged media).
  • When driving, check that the sound does not interrupt and the radio does not restart on its own.

  5) The most common assembly mistakes + how to avoid them

  • Without post-installation diagnostics: the radio may be non-functional/limited – always consider the need to upload to the car.
  • Exchanging antenna inputs or connecting only one antenna: mark the cables before disassembly, the radio has 2 antenna inputs.
  • Damage to pins when inserting: insert the unit straight, do not press on the harnesses behind the radio.
  • Working with the battery connected: risk of short circuits and errors – disconnect/connect the battery in the correct order.

  Reasons why the part is damaged

  • Age and wear of the CD drive (not reading, jamming, noise).
  • Voltage fluctuations in the vehicle network, bad contact in the harness or transient resistances in the connectors.
  • Moisture in the dashboard / leakage and subsequent corrosion of the contacts.
  • Improper assembly/disassembly (bent pins, cracked mounting, damage to connectors).
  • Vibration and long-term stress – micro-cracks in joints, sound interruptions.
