Oh, I thought they all might've had the same number..so I can give you MY code. lol. Anyhow, now that I know all the GSRs don't, if you have the deck on you and can PM me the Serial number, I can call it in for you because I know some people at Honda/Acura. I do know though, that sometimes they don't give the number out unless you have proof of purchase, due to many fraudulent acts. The serial number should be right on top of the deck in white print. Try calling them with VIN# or Serial# and if that doesn't work, maybe I can help ya.
