Some dealers hide the radio code on places like under the ash tray, and other places, but not all dealers do that. It kind of defeats the purpose of having a security code when on almost every Honda/Acura car forum you read posts about where their dealer hides the radio code. Fortunately my dealer never did such a thing and simply would enter the radio serial number into the computer and retrieve the radio code that way. Some dealers charge you for this service but fortuantely my dealer has not thus far. The dealers hide the code somewhere because they like to be able to simply pull the code from the hidden place when they remove power to service work rather than to have to go to the computer everytime. My personaly opinion is if you find the code in your car to put it in a safe place at home and remove it from the car. Checking ebay, even stock Honda/Acura radios can get a price of $50-$100.
