1. Hey. could you by any chance help me with wiring a aivil42p0 radio on bench? i cant find a pinout and looks like what you have on the website with the connectors is different from my variant? its from a nissan juke 2023 it has a new logo and everything. it does not have the immobilizer. on bench it just works for the most part i left it for a few hours and i got a message on the screen the one with the ok.
   1) im looking for a way to turn on the reverse camera (tried hooking pin 8 on 20 pin to ground and to plus and nothing maybe because no camera connected?) this is not important though if not possible on bench.
   2) also to turn on illumination on, tried both pin 9 on 20pin and pin 58 on 40 pin
   3) looking for the aux input. small search is it the pins 33-34 53-54?
   thanks if you could help me it would be much appreciated.

   • Hi. AIVIL42P0 from Juke 2023 wiring on the bench could be found here: https://zelemar.eu/can-filter-installation-on-aivil42p0/
     This pinout is enough to power it up, but i dont have a full pinout for it, so will not be able to help with it. When radio pulled from the vehicle, for the first time it will work on the bench for a 30 min and will get locked

     • hey again, thanks for the reply. its working for me more than 30 minutes. ive let it run all night hoping it would lock so i could unlock it with an emulator but it never did lol. connecting only the pins 19-20 for power and 7-17 as ignition and acc. its working for my purpose but i was hoping to get the illumination on bench to work. oh well i guess no illumination for me.
       anyways thanks again for the reply and have a good day!

       • Illumination control doesn’t use a separate wire anymore, it is controlled over the CAN bus

         • yep, thought it did it since nothing worked.. well thanks again for the reply!

2. Hi,
   I installed CAN filter into LCN2kai (Bosch LCN2K70B00). Installation was easy, I installed it internally, and I can power up unit on bench. But I am putting this unit into car that previously had Visteon G13-P32 unit.
   I cannot power up unit in the car. I see that in the car there is only wire on position which should be CAN H (pin 8, connector M48), but there is no wire on pin 17, same connector, which shoul be CAN L.
   Is there some instruction to make such retrofit to LCN2?

   Thank you in advance

   • Hi,
     Visteon have a different pinout from LCN2Kai, pin numbers will not match one by one. You have to remake connectors in car to match LCN pinout. I don’t have a instructions for retrofitting.
     Please write what is the car model/year and i will try to help with the wiring diagrams.

     • It is Qashqai 2014.

3. Hi, does this emulator work with navara Bosch unit 259155JU0A ?

   • Hi, I haven’t tested myself. But i’m pretty sure it will. As it works on other AIVI units without any issues.

4. Hello, please tell me which resistors I should remove. Remove 2 resistors for CAN_L and CAN_H

   • Hi, please carefully examine pictures provided and you will see.

5. hello can anyone help i have a 2020 Nissan juke j12 radio put chip in not work has anyone done one yet thanks

   • Hi, is this an AIVIL42P0 unit?

     • Sorry for late reply yes this is a AIVIL42P0 out of a juke thanks

       • Nissan Juke AIVIL42P0 use different type locking. You have to connect jumper J1 on CAN filter PCB to work with this type. First time connected with emulator you have to wait for a ~1 min and emulator will learn security codes from the unit and unit will be unlocked after restart.

     • I have done this now problem with power plug thank you

6. Hi, I own a nissan x-trail t32 from 2015 with navi and 360 cameras.
   I changed from connect 3 to connect 4 with a special harness and I get “code red”, not “code green”.
   I can still make the unit unlock by pressing “menu” and ‘back”.
   With your filter will it unlock from “code red” and start automatically?

   • Hi, using CAN filter unit will be unlocked automatically. No delays, no pressing any buttons. Simply it will work as supposed to.

   • Hi Chris did you have to make the harness or did you purchase it from somewhere?

7. Hello, I’m wondering whether you can answer a question I have regarding nissan micra car audio LCN2.0a?

   The audio signal has a subsonic filter and won’t pass anything below 40hz (approx) is there a way to remove this filter? And is it possible to have a circuit diagram which shows me the audio signal preamp terminals? Any help would be greatly appreciated

   • HI paul did you find way to do this radio please LCN2.0a 2014 Nissan the layout on board is different

8. Hi Zelemar,
   I have put the emulator inside the LCN2 but now if i turn the car off, the LCN does not go off.
   Do you know how we can fix this?

   Kind Regards,
   Theo

   • Hi, what radio was installed in your car originally? Some radios goes off by getting ACC/Ignition signals by separate wires, some by CAN. I assume that you have a different configurations, LCN expects this signal by external wire, but your car gives it over CAN or vice versa.

9. Hello, my head unit is clarion QY 8602 and the conectors are the same but there isn t any cable in GND position. Where is the GND cable?

   • Sometimes its not available and GND connected to the chassis of the unit. You can take GND from chassis (there should be wire connected to it), or you can take a GND from other connector. there are some GND points for Camera or Mic. signal connector pinout here

10. Hi everyone!, I just wondered to know how the nissan connect 3 replace with the nissan connect 4 (put the multimedia that with carplay which is without sd card), am i in the right place? Can anyone help me with this question? Thanks in advance!!

    • Hi, You can follow up this link There is a good source of information about converting to Connect4

11. Hello, does the emulator send information about the camera to the radio like the ECU does?
    In LCN2, despite the NTSC camera being connected according to the service manual, the camera does not work. The Manual describes the need to turn on the camera in the ECU MULTI AV system
    MANUAL SETTING ITEM Items
    Setting value SOUND SYSTEM BASE ⇔ BOSE
    CAMERA SYSTEM NONE/AVM ⇔ REAR CAMEA

    • Hi, emulator doesn’t have any influence on camera and doesn’t sent any information related to camera. It send immobilizer unlocking commands only, all other messages pass-thru.
      You have to set camera type with diagnostic equipment, or in some models from service menu.
      How to enter service menu: press MENU and while keep pressed turn right wheel left, right and left. You can find videos how to get to service menu on YouTube.
      From service menu go to Confirmation/Adjustments and then Camera.

12. Hello, I’m all ready to install this into th wiring, can you confirm the colours?, the ignition wire in the noted position is green?, is this correct? Also can you confirm the canl and canh wires? This is for a JUKE 2014.

    • Hi, I can’t confirm wire colors. You have to follow pin numbers as shown in diagrams. Juke 2014 can have a Connect2 or Connect3 navi unit, as it changed from Connect2 to Connect3 on this year.

13. I have found CAN IDs that seems to connect with each other. They start transmit later than others and have some sync every 500 ms. It can be ID like yours 71E and 72E but in smart they are 5D8 and 588.
    BTW, this nav system also has a renault/nissan part number: 259150408R

    8 871 CAN Rx x5D8 8 x00 x07 xFF x00 x00 x00 x00 x00
    9 086 CAN Rx x588 8 x03 xFF x7F x00 xFF xFF xFF xFC
    9 372 CAN Rx x5D8 8 x00 x07 xFF x00 x00 x00 x00 x00
    9 586 CAN Rx x588 8 x03 xFF x20 x00 xFF xFF xFF xFC
    9 873 CAN Rx x5D8 8 x00 x07 xFF x00 x00 x00 x00 x00
    10 086 CAN Rx x588 8 x03 xFF x20 x00 xFF xFF xFF xFC
    …and the 5D8 ID will be changed later on a bench every 30 sec.

    Could you please help me with unlock or advice ? This nav the same as yours. Maybe you could change CAN IDs in your filter and it will work on my system. Thank you

14. Is it possible to use your can filter for this nav unit: Bosch 7503700000
    Its from smart 453 year 2020. Thank you !

    • I have never tested on such unit. As this unit have a Nissan part numbers too, probably it was used in some Nissan vehicles too and might have the same security as nissan radios.
      If you have possibility to check what CAN messages available on navigation unit CAN bus, i could tell will if nissan CAN filter will help. You have to start logging CAN bus before connecting Ignition. As the security messages are not repeated constantly on the bus.

      • Thank you for the answer. This navigation looks exactly like Nissan connect 4 inside. I have CAN hacker. There is some CAN ID that increase their hex number every 5-10 min even without connection to the car. The CAN ID is 5D8 and it increases like 00 0C DC 00 00 00 00, then it change on 0C FE, 08 3C, 08 3E, 08 3D in the same HEX position. I also have other CAN IDs like 559, 314, 423, 5A8, etc, approx 25 CAN IDs.
        Maybe if you tell me which CAN ID do I need to check I will send you a proper number.
        Thank you so much!

      • Sorry, just notice recently “are not repeated”. I have a trace file from my car.

        • You have to look for CAN ID’s 71e and 72e. These ID’s send once on ignition on and not repeated. If navigation unit connected on the bench, 71e send repeatedly for a ~30 sec.
          If you have such IDs on your unit, CAN filter should work.

          • I’ll chek today’s evening and let you know.
            I have a 5D8 CAN ID, looks like it really changes every 30sec with two HEXs. But I don’t know the second ID (like yours 72e).
            Is it possible to update the firmware special for my system ? I’m in the very famous smart club and many smart owners will buy it because the new nav system costs a lot.
            Or is it possible to fix your can filter’s dump on my side if I buy it ? I have segger j-link.
            I can send you my trace file as well.
            Thank you

15. 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.

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

    • Yes, it should be unlocked.

17. 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.

18. 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.

19. 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.

20. 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

21. 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

22. 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.

23. 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
