Thanks so much for your help. In Spain, I was quoted 50 euros for the information I needed. With your service, I received my code in just a few minutes late on a Sunday. Highly recommend for the convenience and savings!

Renault CD serial number format
Example serial number
A123
- Serial number length: 4 characters
This unit uses a 4-character SECURITY (precode) number: one letter followed by 3 digits, for example W417. It is printed on the label on the radio housing, next to the longer 14-character serial number. Enter the full 4-character security number — not the long serial — when ordering.
Blaupunkt-built units have a 14-character serial number (letters and digits) printed on the label or engraved on the metal case, for example BP3301Y1234567 or 3A053278005827. The 10-digit part number starting with 7 (e.g. 7 643 301 316) is also required for the calculation, so make sure it matches your unit. On some labels the serial is split into fragments (e.g. "4 9571489 7643063510 4") — combined, this reads as BP306349571489.
How to enter the code into your Renault CD
Switch the radio on and check what the display shows — this model comes in two variants: If the display shows "RADIO CODE 0000" (rotary-knob variant): 1.

Press the central rotary knob to confirm the code. If the display shows "CODE" and then "0000" (preset-button variant): 1. Press preset button 1 repeatedly until the first digit of your code appears. 2. Press preset button 2 repeatedly to set the second digit. 3. Press preset button 3 repeatedly to set the third digit. 4. Press preset button 4 repeatedly to set the fourth digit. 5. Press and hold preset button 6 to confirm the code. That's it — your radio should unlock right away.
