I have some news. In my case on the Unit ID Information screen there is no SIM ID filled. So there is some difference in 4G TCU first gen vs second GEN in communication. Could someone else confirm that there is no SIM ID filled ?
 
Tried two units now, both 25915-5SN0C on a JDM 2018 LEAF with 360 AVM Cameras and Pro-Pilot, and unfortunately no luck getting the units to fully function.

  • Unit 1 - 08/2019 build (unk trim) with firmware 283C32311E
  • Unit 2 - 04/2019 build Tekna trim with firmware 283C39344R

Confirmed wiring correct and Bosch AV unit is getting all signals such as Ignition, PKB, ACC, Reverse etc

Current Issues
  • 360 degree cameras - No response when pressing the camera button or going into reverse.
  • AV clock won't sync with the dash clock
  • HVAC very slow displaying onscreen changes
  • AV unit does not auto dim with headlights
Following DTC errors on both
  • EV/HEV Can Error EVC-279 (EV/HEV is the cars ECU)
  • EV/HEV Can Comm Circuit
  • AVM Can Comm Circuit (possibly incompatible with the JDM AVM module?)
  • Meter Can Comm Circuit (Meter = dash cluster)
Interestingly on the QY Clarion unit, which is actually a UK unit works flawlessly with no codes. I have to set the Camera's as FAP not AVM for them to work.

Unsure what FAP means, maybe related to Pro-Pilot Pilot in which case because you can't set it in the Bosch unit is likely the camera issue. If I set the Clarion unit to AVM they don't function at all.

I think at this point both firmware's are not compatible with the JDM LEAF control modules and dash cluster, and likely the camera setting not being set to FAP.

Hey, if anyone inside the EU is in interested in this mod, I have my 8" headunit + adapter cable (including the Zelemar unit!) for sale. Sold my Leaf last year.
Fully working (just note the caveats in first post) and ready to go for a Tekna level Leaf (360 cameras, Bose etc.) with no extra configuration needed.

Model number: 25915-5SN0C

Shoot me a DM. Asking for 250€ including postage.

Hi all

late to the party here but just wondering if someone can do me a favour. Ive tried wiring up the harness and I think my skills leave a lot to be desired but I wonder if anyone is willing to test my 8" unit that I bought to check its working. It was from ebay and although it said working I cant verify it.

Obviously I would be willing to drive to you (south east would be preferable if possible, Im in Hertfordshire).

Also if anyone is better after subsequently at wiring a harness for me I would be willing to pay! I need to get this working so I can sell my leaf and get a half decent amount for it!

Running a 18 plate tekna.

Cheers

Phill
 
Hi after switching from 7" to 8" unit i have these faults on diagnostic menu , can someone help nie with that ? The antenna is most important

Hi Mike

Did you do the wiring yourself or get a harness made elsewhere?
i did it, however the antena is separate plug with 2 wires and i needed to take out pins from plug because it wasn't fit to 8" headunit
the unit comes from nonBOSE car and is set to 360camera
my car has BOSE and 360 camera with self parking
so for now audio is loud as hell and no camera view at all
i need to visit dealer but i doubt that they can help me with antenna

Wasnt there a thing earlier in the thread that says you need to shave down the antenna plug and it will fit?
 
well, i wanted to leave plugs untouched , so i take out pins, cover it with shrink tube and connect to new headunit
 
Сейчас попробовал два устройства, оба 25915-5SN0C , на JDM 2018 LEAF с камерами 360 AVM и Pro-Pilot, но, к сожалению, не удалось добиться полной работоспособности устройств.

  • Unit 1 - сборка 08/2019 (unk Trim) с прошивкой 283C32311E
  • Unit 2 - сборка Tekna 04/2019 с прошивкой 283C39344R

Подтверждено правильность проводки, и AV-блок Bosch получает все сигналы, такие как зажигание, PKB, ACC, задний ход и т. д.

Актуальные вопросы
  • Камеры 360 градусов — нет реакции при нажатии кнопки камеры или включении заднего хода.
  • AV-часы не синхронизируются с часами приборной панели
  • HVAC очень медленно отображает изменения на экране
  • AV-блок не затемняет автоматически фары
Следующие ошибки DTC на обоих
  • EV/HEV может вызвать ошибку EVC-279 (EV/HEV — это ЭБУ автомобиля)
  • Схема связи EV/HEV Can Comm
  • Схема связи AVM Can (возможно, несовместима с модулем JDM AVM?)
  • Цепь связи Meter Can (Счетчик = приборная панель)
Интересно, что устройство QY Clarion, которое на самом деле является британским устройством, работает безупречно, без каких-либо кодов. Чтобы они работали, мне нужно настроить камеру как FAP, а не AVM.

Непонятно, что означает FAP, возможно, это связано с Pro-Pilot Pilot, и в этом случае, поскольку вы не можете настроить его в устройстве Bosch, скорее всего, проблема с камерой. Если я установлю для Clarion режим AVM, они вообще не будут работать.

Я думаю, что на данный момент обе прошивки несовместимы с модулями управления JDM LEAF и приборной панелью, и, вероятно, для настройки камеры не установлено значение FAP.
Здравствуйте. У меня такая же проблема, вдруг, перестали работать все камеры, и не реагирует на кнопку. Что делать?

Did you manage to get the cameras working?
 
anyone knows, is there a difference in wiring between 360camera and 360camera+self parking ? i took 8" headunit from car that had only 360camera to car that have self parking and i have no picture from any camera

I got the same issue. No picture from cameras and I got the self parking option in my car. Hopefully the dealer could code it somehow

I would take a look at the Nissan service manuals at this point.

They're available at https://www.nissan-techinfo.com/ which is where I got the details used to make the pin diagrams in the first post. It costs $20 for 24 hours but it's well worth it.

Now that I think about it, I suppose the control units for cars with auto park and without are different.

If AVM stands for Around View Monitor (cars without autopark), could FAP stand for F[...] Auto Park in the Nissan manuals (and software?)
Man if you guys find different pinouts in the service manuals for FAP cars that'll change the game and explain so many camera incompatibilities lately.
