Boubasak The only Honda radio codes that are available to be calculated for free from anywhere on the Internet will be radios made by
BLAUPUNKT. These will have a Serial Number beginning with BP and another number beginning with 7 *** *** *** found on a label on the radio casing
UNFORTUNATELY ... NO OTHERS !
So you will be wasting your time posting code requests here for any other make.
BLAUPUNKTS ONLY with a BP Serial Number
=================================================
For EVERY other HONDA radio made by one of the other manufacturers then visit the website below

If they cannot provide your code then you will have to try your HONDA Main Dealer or a Decode Service who will plug it into a laptop and electronically read/recode the memory chip (EEPROM)
