Hi there, Last week installed a new battery to my megane scenic 2004 (53), to my surprise there are no code(s) or whatsoever on any of the car manuals.
I've tried a couple of pre-code softwares without any success.

Could any of you de-coding experts give me a hand here?

radio details:

model: 22dc277/62
r590 security
rn277f40755420
prod no: fd0804490755420
security number 8200256141tr590

much appreciated.
