We were looking to import some head units that were android and compatible. When we get the first samples in, I can post about it. There is an Open Vehicle replacement for Nissan Connect. Works on older models as well when the 3G no longer works.

see my post. I replaced my headunit with Android. not 100% perfect

Can you make picture of another failed canbus decoder?
Or type partnumber.

Yours is FST-BNR-NS02 and is working for 80%, it is mean for Teana, Murano, X-Trail 2013-2017

That two canbus will not work with Nissan Leaf 2018 ZE1. This is the Smarty Trend send to me
The wire set it comes with also doesn't work as well

Following up to this, I was able to wire everything up, and the 8 inch 2022 unit (2591A-6WK2C) worked however looks like it had some damage on the screen on the left hand side.

Got some canbus errors too, but after cross checking my wiring with the ones linked here before, it looks like I need to swap the M Can-L TRM and M Can-L lines, same with the Can-H lines

Also USB didn't work for me, I assume I need a newer USB C port compared to the combo Type A and AUX mine has.
I did notice my original unit had two USBs connected to the head unit, anyone know what each one goes to?

Other thing to note seems like the connector on the radio AM/FM antenna has physically changed.
Old was GT13SH-2/IS-HU connector, new connector is GT13SHB-2/1S-HU. De-pinning this connector seems tough on pin 68/69

Looks like the EV specific features are missing too, might be because of those swapped canbus lines I imagine?

Just following up on this got a replacement 2019 unit with and mostly working fine. Issue now is no reverse camera at all.
In the diagnostics menu the reverse signal is being sent, but it doesn't switch over to the camera view.

Very odd considering it works stock, naturally, and with the 2022 unit as well

Understood, maybe the wiring harnes is difference.

I have ordered android hu and will receive tommorow.
Acording seller has send Simplesoft NS-SS-04A canbus decoder. (same as your first picture)
And before I install new unit I have to check wiring harness first to determine for which unit is (7"or 8" wiring).

Please keep us posted.
 
Hey folks I'm still at a loss here, second 8 inch unit from 2019 has been installed, but reverse camera does not work at all, and microphone does not work either.
Reverse Camera worked with the first 8 inch unit, so it's wired correctly unless the wiring changed between 2019 and 2022. I've checked the wiring diagrams again and they're the same

Microphone is wired correctly, but I'll have to recheck if my soldering was okay, may just use Wago connectors this time.

Also getting a CAN Communication error, and MCH1 USB error, which I assume is the Telematics USB? EV Connect works fine so I don't know if it's complaining about that, or an actual USB port as this one shows two USBs in the audio menu, I've plugged in a Micro USB to Type C and routed to glove box for my AAWireless dongle, works fine.

Looks like a lot of the functionality is hidden behind Can communications 🥺🤷🏾‍♂️
 
Anyone know where to get service manuals or pin outs for JDM Leafs?
They got a larger unit in some of the later model Leafs, similar to more modern Nissans with the 9 inch screens. They have a more connections, I assume to support some sort of TV function that naturally wouldn't work outside of JP, it's hard to see from the pictures.

I just bought a 2022 JDM with this exact unit. The guys I bought it from changed the language to English, but otherwise it's all JDM... wrong FM frequency range, unusable maps (Japan only), built-in TV tuner for Japan etc. I have the wiring diagrams for the ZE1 "Connect 3" NAM units, and the pinouts seem pretty similar. But there doesn't seem to be much info out there on the software hacking for these things. I can't figure out how to change the maps, or change the frequency range, for example.

I'm keen to learn if anyone finds info about hacking these things, and/or if it can be replaced with a different model without losing a bunch of functionality.
 
I have received Android HU.

Wiring harnass seems designed for 8" unit.
So it wil not work upgrade from 7" unit to android unit.
You'll have to re-pin harnass or use adaptor using Danep82 wiring diagram.
And add ground pin to chassis, orignal 7" harnass has missing ground pin at my car.

Canbus works, doors, steering angle, steering button, no ac information.
(right side) Phone button act as mute, and other one (I believe phone list).
(left side) volume, next, prev works.
Canbusbox is from Simplesoft NS-SS-04A and is set to Nisssan Trail (17~18 middle high) or (17~ all oversea) works.
I haven't tried all canbox type settings, will do later.

Avm camera did not work first time, I have to change factory settings (hidden with pascode)
But now it works only in reverse with steering angle line, but it does not show to avm when close proximy. (canbus issue?)
Ignore red X, it has already been there, and auto parking is not working (I don't use cause it is slow :-D)

Bluetooth is hard way to connect obd2 device for LeafSpy pro.
On board 4G works, carplay works, remote battery check or remote a/c control works with 3th party app (using QuickLeaf app).

My unit is K4811, 6gb, 128gb.

I will post new thread soon.

Maybe you can change trim/configuration with this tool.
But you cannot update firmware.

Maybe hu is defective??

It's possible, seeing as this is a replacement unit from the first one that came in with a damaged screen I'd hate to bother the guy again.
I suppose I have nothing to lose.
The CAN error, and USB1 error don't seem to be affecting anything that I can notice. I can still use the EV Connect app to check range and AC.
So really it's just the reverse camera not working at all on one unit, and USB port not working on the second unit.
 
I have tested with 3 canbus decoders.

First one is Simplesoft NS-SS-04A.
Door info works, steeringwheel button work but slow, no A/C info, reverse angle line work (in reverse), no auto switch to avm when close to object,
remote battery check, start A/C work.

Second one is Raise G-RZ-DF57. (currently using)
Door info does not work, Steering wheel button work, no A/C info, reverse angle line work (in reverse), no auto switch to avm when close to object,
remote battery check, start A/C work.

Third one is Raise DF-RZ-13.
Door info does work, Steering wheel button work, no A/C info, reverse angle line work (in reverse), no auto switch to avm when close to object,
remote battery check, start A/C does NOT work.

Last one is on the way it is Hiworld NSF1.20.

Got HiWorld canbus box, and installed.

After testing settings on list.

Got almost A/C info working but with errors.
Source IC works (FM, USB, AUX, etc), and time sync too.
Steeringwheelbutton works but Prev is Next, Next is Prev, Voice = Phone list, Phone = mute/unmute.
Door info works.
No auto switch to 360 camera when parking or proximy warning.

I have let HiWorld know issue and gave canbus data to them. (they have forum)

I hope this canbus box (HiWorld) will works in future on Leaf.
