I have just bought an Espace 2004 and there is a CD changer with what I suspect is a radio hidden behind it, installed behind a compartment in the rear of the car. It is obviously designed to be fitted other than in the dash board where there is a sat nav installed. .
On the plastic casing in which the CD changer sits (I cannot even get to see what I believe is a radio behind) are what seems to be two numbers:
AL9RN851032677 (the 85 could be BS or any combination)
immediately below is a second number
C41032677
Then a sticker on the underside of this plastic casing is a bar code and number:
C9RN85ZC41032677
you can see that most of this last number is the same as the first of the first two numbers.
The security code itself would be brilliant, but any thoughts about what I can do would bea big help
