Whenever the battery is disconnected or power is interrupted, the audio system will require input of the anti-theft security code. This code should be with the owners manual or on a sticker affixed to the inside of the glove box. If not, the code must be obtained by the manufacturer or your Acura dealer using the VIN number and or serial number of the audio unit.
