Patman- take a ride to Acura in Groton. Bring your radio with you. They'll give you a free code IF you show proof of ownerage. While you're down there, stop and talk to Colby (ur31337) in sales if he's not busy. He can pretty much answer any questions you may have.
PS: explaining your sitch will help you out too there. They're good people down at Antonino.
