I had the same problem......I found that when I turned the car on but not the engine then press the 1 and 6 keys on the radio at the same time it gave me 10 digit code for example L8745 U4564 ..........write this number down as it is the serial number for the radio. take the 10 code and call your dealership or the 1800 acura number for your local area and they should be able to give you the code..........the dealer would be charging you to remove the stereo to give you the serial number but the 1and 6 key is free..... once you have the serial number the unlock code should be free!!
