166 code

Hi all,
Can any one assist with a code for my 166.
BECKER KW:27/00 65 31 35.20.12
BE2580
SERIAL NO. Y5031632
BARCODE READS 2580G%0Y5031632

My local car audio center tried but each time came up with the wrong code.

There is other info on the unit siemans but I think this may be for the sat nav ?

Cheers

I think the BE2580 has its own algo but have you tried 4365??

thanks for the info I will try it tonight when I get back from work.
Cheers

Hi tried 4365 no joy, but appreciate your input,
Any other codes to try or solutions would be helpfull.
Cheers
