Entering Security Code
Anytime the navigation system loses power, you need to enter the 4-digit anti-theft code on the navigation system display. The 4-digit code is located on a small card that was given to the customer. Enter the 4-digit code, then select Done.
If the navigation system anti-theft code is missing, use the interactive Network (iN) to lock it up. You 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 gives you the serial number without removing the navigation unit.
The iN 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, replace the navigation unit.
When replacing the navigation unit or audio unit, make sure you give the customer the new anti-theft security code.
