VOLKSWAGEN Radio And Navigation Systems: Notes
The anti-theft coding electronically prohibits unauthorized individuals from starting the unit again after it has been removed. This anti-theft code is also called the radio code or security code. Security code means that every unit with anti-theft coding has been programmed with its own code. This security code is not active from the factory. If a device card is present, the security code is on it. If the device card is not present, the security code can be requested from the central database using the Vehicle Diagnostic Tester. Refer to RADIO CODE, CHECKING WITH Vehicle Diagnostic Tester .
If an incorrect code is entered while canceling the electronic lock, the entire process can be repeated just one time more. If an incorrect code is entered once again, the unit will lock up for about one hour. It will not work. After an hour, during which the unit must remain switched on, the display will go out. The electronic lock can be canceled as previously described. The cycle: 2 attempts, an hour locked, begins again.
