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 client. Enter the 4-digit code, than select Done.
If the navigation system anti-theft code is missing, get the serial number from the navigation unit and use the iN to look it up. You do not need to remove the navigation unit. See ANTI-THEFT FEATURE .
When replacing the navigation unit or audio unit, make sure you give the client the new anti-theft security code.
