If you cannot see your number it is because many 6000 CD units do not show the series on the screen. If this is your case, you have to go to method 2. If instead of starting a cycle, your radio shows a piece of unique information that begins with the letters "FD", then that is the number to get the radio code. Example: FDC2005M123456 Note: In some random units, only the serial number appears when pressing 1 and 6 and it has this format: FDD2004V120122. We can also use it to generate the code. Hold down the number buttons 1 and 6. You can stop pressing them once something appears on the screen.

The number is only displayed for one second at the end of the cycle you just started. A valid serial number always begins with the letter V (V Series) or M (M Series), followed by 6 digits. Taking a video with the mobile would help you see it.
