1. Hi How Can i buy a Can filter to a LCN2 ? And How much does it cost ? I live in Denmark. Thanks Ronni

   • Hi. You can buy it in webshop here: NISSAN CAN filter – security emulator

2. Montado en mi leaf EZ1, Y funciono a la 1º…. 🙂 .
   solo tube algunas dudas con las conexiones, que me resolvieron en el mismo momento.
   envio rapido atencion muy profesional y amables. para mi un +10.

3. Does it allow to pass other communication with BCM or with AVM module (bird view cameras), setting up a clock or display what is currently played on the radio on combination meter display?

   • It passes all CAN communication with other modules. The only message it filters out is a security challenge-response message, which the emulator replaces.

     • Hello. I have additional question. When you tested emulator with navigation did You check if camera button works without any camera connected? I have secure system locked green. I didnt connect V-Can afraid of change green level to red level. I’d like to buy your emulator but i don’t if my navi don’t react when pushing camera button because not all wires connected or it doesn’t react because is broken.

       • Hello,
         If a camera is not connected to the navigation unit, the button will not work. The camera button works only if the camera is connected to the unit and car speed is lower than ~10 kmh.

         • Ok. I ordered one a while ago. For confirmation. I connected avm module with navi with v-can and camera image signal and shield, also to both ignition, battery, gnd and reverse signal. To avm I connected one camera. Camera button on navi didn’t work because i didn’t connect v-can to car and didn’t connect speed signal, yes? If i connect all signals in car with navi and avm module and can emulator to navi everithing should work, yes?
           What tool should i use to soldering wire with can emulator and what maximum teperature is allowed?

         • Around View Monitor (AVM) on Nissan Leaf is connected to the navigation unit CAN bus, power supply, reverse signal, AVM detection signal, and video input on navi unit.
           CAN filter connected to navi with AVM doesn’t influence AVM and everything works as supposed.
           Soldering must be done in accordance with all standard soldering techniques. Temperature ~300 degrees C for several seconds. If you don’t have experience, ask somebody for help to avoid damaging the pcb

4. Hello can I use it for unlock a Qashqai J10 navi ? The model is CCA 1452E
   Thank you

   • Hi. I haven’t tested it on this model, so not sure will it work there.

     • I tested on Qashqai J10 with navi…it’s working great. Thank you ZELEMAR. Before I found you I tryed everythig and nothig worked. I strongly recomand

5. Hello again. Everything works, navi juke/pulsar lcn2kai unlocked. But i want to ask whether it’s normal that amber light is blinking? At first connection it was blinking almost 1 minute and it didn’t unlock the navi. For the second time there was no blinking and the navi started unlocked. Third time it blinked once and later there was no more blinking. I simulated ignition signal

   • Hi. Amber light blinks when power is applied and the necessary CAN message is not received. When necessary CAN message received and navigation is unlocked, led goes off.

6. Hi. Does the unit work on the bench, both with internal, and external installation?
   And what happends if C1L and C1H is not connected to the car?
   I have a Nissan Leaf without Vcan, only Mcan.
   Is it possible to connect C1L and C1H to CanH and CanL at the instrument panel?

   • Hi, Yes, it works on the bench with both installations. To bypass security, it is enough to connect CAN2 (C2L&C2H) to navigation unit, and CAN1 can stay not connected.
     If C1L and C1H is not connected to the car, the navigation unit will not receive messages from other control units, and some info will not be displayed such as battery info.
     If Vcan is not available in your wiring at the navigation connector, you can try to connect it at the instrument cluster, but I never tried it.

7. Hi, what’s the message it’s sending? I thought the device is locked to the VIN number of the car does this change the VIN number?

   Also If the can lines are not cut and just CAN2 is connected into the existing wires (in parallel) will it mess the car security up?
   Thank you

   • Device is not locked to the VIN. Its a challenge-response based thing between the radio unit and bcm. If CAN bus will not be cut, nothing will be messed up in the car, only the navigation unit unlocking will not work, as it will receive conflicting can messages from the emulator and car.

     • Hi, Thanks gor a very fast reply!
       So I guess the BCM asks the NAVI unit a question and if it doesnt have the correct answer saved to send back then the BCM locks it out of the system.
       Just worried about cutting the wires but that does make sense with conflicting messages thank you.

8. Hi, if it has a red lock code, will the radio be unlocked after applying the NISSAN CAN filter?

   • Yes, it should be unlocked.

9. For those who want to mount this filter on the PCB of your LCN2Kai Nissan navigation, please check after installation if you have 120 Ohm resistance between both CAN1 H/L lines and CAN2 H/L lines. In my case I had to mount an extra resistor between CAN2 H/L lines and also swap the position of the wires. I think on the external schematic it is correct. Communication with the supplier was very good and they helped me. Now everything works ok. Maybe they will post the updated schematic for the internal mounting.
