Entering Security Code
Any time power is disconnected from the navigation unit, the 4-digit anti-theft code must be entered on the navigation system display. This 4-digit code can be found on a small code card that was given to the client. Enter the 4-digit code, then select "Done".
If the navigation system anti-theft code cannot be found, use the interactive Network (iN) to look it up. You will need the serial number for the navigation unit to do this. You can view the serial number by entering the diagnostic mode. Select "Unit Check" from the main menu, then the "Navi ECU" diagnostic screen. This allows you to get the serial number without removing the navigation unit.
The i N may display more than one code for a given serial number. This is because serial numbers are not unique. You may have to try more than one 4-digit code. If no code is shown, or if the code(s) given do not work in the navigation unit, contact the Automobile Warranty department. If the code "0000" works, then replace the navigation unit.
When replacing the navigation unit or audio unit, be sure to give the client the new anti-theft security code.
