NISSAN navigation and radio security
European NISSAN navigations and radios are equipped with a security feature preventing to install unit in another car. They are preprogrammed to the vehicle security system. Each time on system power-up unit validates security codes with car security system and if codes doesn’t match, unit will not work.
Navigation unit installed in vehicle without security feature or powered on the bench will show message “Please Wait” while waits response from security system.
If response from vehicle security system is not received within 30-60 seconds, or response is wrong, message “SECURE” or “SYSTEM IS LOCKED” will be displayed.
As a solution for this problem comes CAN filter – emulator. It allows to install Nissan navigation or radio unit to another European vehicle, retrofit USA market vehicle with European unit or test it on the bench overriding security feature.
CAN filter can be installed inside the navigation unit or connected to the navigation unit wiring.
