I just fixed the same problem today. You will have to contact an Acura Dealer, The one of 8 that i called which was the only one willing to help, was Acura of Rochester NY, (585) 385-5544. Okay, Get the dealer on the phone, turn your car on, Hold down the 1 and 6 preset radio buttons, a series of numbers will appear, the first w/ a U in front of them and the second set w/ an L in front of them. If you give the dealer those numbers they will Give your the code. Other dealers will try to tell you to remove the radio, or charge you $100 or more to do this. GOOD LUCK!
