Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Entering the Security Code
Any time the navigation system loses power, you need to enter the 4-digit anti-theft code on the navigation system display. This 4-digit code is located on a small code card that was given to the customer. Enter the 4-digit code, then select Done.
If the navigation system anti-theft code is missing, get the serial number from the audio-navigation unit and use the interactive Network (iN) to look it up. You do not need to remove the audio-navigation unit. See Anti-Theft Feature.
When replacing the audio-navigation unit, make sure you give the customer the new anti-theft security code.
