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.
