2012 Acura MDX Owner's Manual - Page 315

Radio Theft Protection If your vehicle's battery is disconnected or goes dead, the audio system disables itself. If this happens, you will see ''ENTER CODE'' in the frequency display next time you turn on the system. Use the preset buttons (Icons on models with navigation system) to enter the five-digit code. The code is on the Anti-theft Identification Card included in your owner's manual kit. When it is entered correctly, the radio will start playing. The Anti-theft Identification Card also lists your audio serial number. It is best to store the card in a safe place at home. In addition, you should write the audio system's serial number in this owner's manual. If you make a mistake entering the code, do not start over; complete the five-digit sequence, then enter the correct code. You have ten tries to enter the correct code. If you are unsuccessful in ten attempts, you must then leave the system on for one hour before trying again. The system will retain your AM and FM presets even if power is disconnected. NOTE: If you have a My Acura account, it is easy to retrieve the anti-theft code online without having to access the serial number. Canadian owners If you lose the Anti-theft Identification Card, you must obtain the code from your dealer. To do this, you will need the audio system's serial number. If you do not have the serial number with you, ask your dealer how to retrieve it. Models with navigation system You need to enter the same code for the navigation system to reactivate. Read the navigation system manual for details. U.S. owners We recommend that you register the security code at My Acura (myacura. com.) If you lose the Anti-theft Identification Card before registering the code at My Acura, you must obtain the code from your dealer or https:// radionavicode.acura.com/. To do this, you will need the audio system's serial number. If you do not have the serial number with you, ask your dealer or go to https://radionavicode.acura.com/ for information on how to retrieve it. 308
