============================================= If you CANNOT find a code written on the radio or on a card in the glovebox (or similar "hidden" place ) then please read on
HONDA do not make radios .They only affix their badge onto radios made by the large manufacturers (ALPINE , BLAUPUNKT etc).
The majority of HONDA codes are NOT readily available as access is required to the original factory database which is not commercially available to buy
HONDA radios are made by the following manufacturers
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
Plus older radios made by
PHILIPS ...Model 22 DC681/02
Early ALPINE (Model numbers beginning CM+ + + + )
UNFORTUNATELY ... NO OTHERS !
