NISSAN CAN filter installation

NISSAN navigation and radio security

European NISSAN navigations and radios are equipped with a security feature preventing installing units in another car. They are preprogrammed to the vehicle security system. Each time on system power-up unit validates security codes with the car security system and if codes don’t match, the unit will not work.

A navigation unit installed in a vehicle without security features or powered on the bench will show the message “Please Wait” while waits for a response from the security system.

If the response from the vehicle security system is not received within 30-60 seconds, or the response is wrong, the message “SECURE”  or “SYSTEM IS LOCKED” will be displayed.

As a solution for this problem comes the CAN filter – emulator. It allows the installation of 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.
