i was at dealer and asks for coding my headunit (i need to add propilotpark and bose to my HU) and they say that this is not possible with NISSAN CONSULT :(
Hmm maybe it is. Like mine does not show all round view, even configured.
And there is no way change camera settings in service menu.
All keys are greyed out.

Unit is 25915-5SN0C

Now I think maybe my Openpilot device cause error configure settings.
To use Openpilot I have to disable steering assist, and so pro pilot parking are disabled.
HU says auto parking is not available, when I enter camera in settings (not service menu)
I will try after few days re-configure.
 
Leaf app (Nissan Connect EV) stopped working, I have to register unit ID.
But 3th party app I'm using is QuickLeaf, and I can check battery (fast result) and remote A/C.

do you have any view from cameras ? when you push button CAMERA ?
what about cable ? did you change any pin connection ? or just made changes like Danep82 in his diagram

I have all round view system with pro pilot parking assist.

Screen goes full black when in reverse and or camera button.

Sometimes I saw very short message from reverse to drive.
"Parking assist is not available" or so.

I made adaptor from Danep82 diagram without Nissan CAN filter.

I will check pins later.

Edit: ic compass is not working.

ok , so we have the same setup, also same behavior of the equipment, only difference is i have zelemar emu installed and you reprogrammed keys and immo,
what about audio ? i have HU from nonBOSE and my car has BOSE audio , everything is loud as hell and parking sensors almost break my ears

It was same as you.
Hu was configured to rhd, base 6 (nonbose), rear.
And I did reconfigure to lhd, bose, avm+pa.
Now sound is good except all round view.
 
lucky you , i cannot find any garage with device that can reprogram HU for BOSE , rest features like compass or audio source id is irrelevant for me
 
Yea, btw I found Launch X431 creader elite for about 100 usd. (they sell difference version by brand)
It has full access.
I have ordered Nissan version one. (you can add other brands by paying in the app)

So I would not need to go friends garage to check dtc or coding again.

I would not using programming/coding at motor, battery or so.
Only for comfort things, add or re-register keys.

Great , you are sure it has that functionality? Can you send me link to the shop? I will buy it too
 
I got it and tested.
Shame, all round view does not works.
HU configuration says AVM or AVM+PA, but inside system it is set to lvds-rvc which is rear view camera.
Maybe it is not supported, when I tried from avm+pa to rear, I got error programming.
I can only change between avm and avm+pa.

I have to recheck again on camera signal pin. (orignal 40 pin on pin 40, and pin 49 on adaptor)
Based on Nissan-Techinfo.com

But other settings like bose or base speaker works.

And it can calibrate avm system under AVM module, but I won"t touch settings.

And by the way:
Info - NissanConnect Services - Information Channels - Info from Nissan - Account Information - Car Pairing Code.
Car Pairing Code has disappeared, so HU must know it is older model car.

Normally it would be Multi AV, but here it is Audio and Video (AV).
Fault code is lvds connection error.

I am giving up, I think lvds-rvc is locked (i think wrong protocol signal or so), or my diagnose-tool has limit at camera settings.

But I have found and ordered other one is 25915-5SR0B for 290,- eur incl shipping, based on other listed parts it has bose amplifier, sidemirror has camera, no park assist, so it is set to avm.
Without park assist is ok, I want use avm for parking, and since I have Open-pilot installed so park-assist is disabled.

Should I use initial reset or leave untouched? (or just only delete data logs and user data manually, not the whole system reset?)
 
So i checked mine HU with other leaf 7" , that has avm (mine has avm+pa) and this HU works and show all cameras , so i guess wiring is ok for , but there must be diference between 7" avm vs 7" avm+pa - if we could have schematics for them we could figure it out the diference and apply to 8" setup
 
I don"t think it is wiring setup. I rechecked and they are all good. I think protocol signal is difference.
And 8" HU is still set to LVDS-RVC, and I cannot change to AVM or AVM+PA. (under HU service menu)

It stays on LVDS even configure camera settings.

Even set configuration to AVM or AVM+PA
It must changed to something called AVM, but it does not.

On diagnose it is set to avm+pa, HU (very short display message says "park assist is unavailable", then go black, because steering assist is disabled to use open pilot), and under AVM (just no message and black screen)
So it must inside HU that is locked to rear view camera only (LVDS).

As I say I found another one, and I was looking for compatible by looking other partlist from that car.
And I saw it has bose amplifier (so bose), side mirror has camera (so has AVM), no park assist switch (no AVM+PA)

Damn!!!!

I think I know how I did. (Not sure)

In configuration I tried write to AVM, then write to AVM+PA.
But don't turn off car

Then push and hold 10 sec or longer on push (left round knob) untill device reboots.

Edit now I got lost image after start the car and put into reverse.

I think hu is defective.
It is like configuration/protocol signal is lost after some time restart car.

I have this settings
At last picture.
It is set to base (non bose), and about avm I don't know.

I got avm working by writing configuration and reboot HU only.
Weird about that under service mode it say LVDS.
But after turn power off(key off) well like 15 min shopping and back to car then it won't display avm.
(Error I saw displaying map before going black)
 
I ordered this x431 Elite , i have question, can i reprogram keys with this device and remove ZELEMAR emulator ?
