Ok cool thanks.

I dont see a place to add one. Just the memory card slot.

Hi all!

Just registered to say thanks to everyone here for beautiful information source I found in this thread.

And specially for Assad: if you ever have a chance to travel in Moscow - please know you will find a "six-pack" or any you prefer better waiting for you here as well :7:

Last week I finished with C500+ installation to Z52 Rusmake Top (same with 360 around view, headrest LCDs and Bose amp) having 360 view, sonar warning sounds continue working almost same as it was with NissanConnect unit.

This was done by installing additional NanoPLC Canny7 controller with CAN bus interface (www_cannylogic_com/c7/) to monitor ACC state, gear lever, speed, sonar warning state and additional button pressings. According to these conditions Canny sends control messages to ABM module, turns on buzzer and generates "rear shift" signal for headunit to display 360 view.

The original idea was not mine, I only improved it by rewriting Canny7 software from the scratch.

This approach is really works with almost any head unit but requires a bit advanced level of installation skills

I've published report on (aeinc_ru/photo/navi4/) but it is in Russian only, sorry...

P.S.: And sorry for broken links: looks like I'm too new here to post something suspicious

Welcome to the forum AE_, hope to read more from you.


Thanks for the info, never heard of that module, I just visited the page and it looks really promising with everything you can do with it.
Looks like you need to program the head unit to be able to interpret all those code from the various channels and to display it on the screen.
Also how would you know all the different canbus codes. For example 'Door Open', how would you figure out the canbus code for that event, since this must be universal on not only made for nissan.
I am guessing the Chinese head units use this approach to program their canbus decoder.


The C500+ was my second choice, but they are still at android 6.0, but someone here did buy a C500+.


Thanks again for the info...

So apparently I’ve either done something terribly wrong or have not connected something right. I got everything back together but the car will not start. It acted like the battery was low at first but then it stopped doing that and just acting strange in general, cycling on and off by itself over and over.

So I took it all back apart and disconnected the new head unit. It stopped all the frantic beeping and weird cycle on/cycle off stuff but now says no key can be detected even though I have it in my hand.

I don’t know a lot about electronics but I’m guessing maybe its a bad ground? Or blown fuse? Any ideas?

Hi Boredfish,
There is a white box right below the radio, make sure you connect that back, that has nothing to do with the radio, it is for the ac. Also do not mix the connector on the white box, because that one is also a 40 pin connector, and can be mistaken with the 40 pin connector that goes into the radio.

Do things one at a time:
Remove your original radio
Do not disconnect the white box below the radio. If you did, reconnect it...
Turn on the car, make sure everything looks good, turn on ac to make sure it is working.
Turn off the car
Plug in your new radio, 2 white connectors, 1 is 20 pins, the other is 40 pins and the radio antenna connector, that is where your ground comes from.
Turn on the car and make sure you can hear the music.
Turn the car back off and connect the rest of the connectors, USB, GPS, etcc...
Reassemble everything....

The unit powers on just fine and everything on it works: Radio, WiFi, even steering wheel controls. But the car will not start. Take the radio off, car starts no problem. Idk man, seems like there is probably one little thing off somewhere but I have spent the better part of the afternoon trying to figure it out and no dice.

Hi BoredFish,
Ok, I see what you are talking about, also saw your video.


Can you connect just the 20pin connector and the radio antenna (GND), and see if that works.
With only the 20pin connector connected, you should get sound at least. The 40 pin is for your canbus communication such as the steering wheel control, backup camera, etc...
If you can get the car to start with just the 20pin connector, then that means they messed up the canbus communication, either miswired it or programmed it wrong.
Canbus can send information back to the car from the head unit, such as the time, the radio station you are listening to, the music track info, etc... that info shows up on your dashboard; and if this communication is not correct it can send wrong info to the car and the car won't start.

 

[assad]

Also I forgot to mention, in the head unit settings, under factory settings, under canbus, make sure #37 Nissan Teena is selected as shown on one of thread above from Luinoz (password is 126).

Yes, with just the 20pin connector the car starts but the radio doesn’t power on. I started the car then connected the 40pin to get power and checked the CANBUS settings, it was on 10, not on 37 so I changed it to 37. The car then allowed me to stop and start a few times so I thought the problem was solved. After attaching the USB, GPS, etc... I set it in the dash and thought, let me test it one more time and it went right back to the same problem as before. Double checked CANBUS which was still on 37. Played around with it some more, even took off the battery cable to let it clear it’s memory but nothing. Howeverthat definitely narrows down the problem to the CANBUS specifically. I’m going to go check the wiring against some previous posts otherwise I think I’ll have to get them to send me a new one.

Sorry you are having these issues with your new head unit, seeing how excited you were installing it.


With the 20pin connector connected, you need to make sure you also connect the radio antenna connector, this is where the unit gets its GND, the unit should power on with only those 2 connectors.

The 40 pin is only used for CANBUS communication and backup camera.

So you narrow it down to the CANBUS located on the 40 pins. It is most likely sending some code that the car does not like or cannot decode.

There is a small plastic box (canbus decoder) with a label on top, can you take a picture and maybe someone here with the same unit can compare if it is the right one.

Either the CANBUS decoder box is not the right one/not programmed correctly.
Or they miswired the CANBUS decoder.


Also check the software version on your unit (under About Unit) and post it here, Luinoz can verify if you have the latest, since his unit is working.


I am guessing you have the 201? SL with Bose...

Then something is definitely miswired because the radio does not power on with just the 20pin.

20pin connector + Radio Antenna


There is a 3 pin grey connector on the unit with a radio antenna connector, you need to connect that one to the car grey connector, this is where the unit gets its GND.

 

[Luinoz]

My 40 pin does not have the red cable next to the purple. The two green ones on mine next to the camera cables don't need to be there. The 20 pin are different too. The cambus looks the same. Try with out the cambus

 

[assad]

Please see the diagram below.


The connector I circled is for the radio, also this is where the unit gets its GND.


Connect that to the grey connector from the car and the 20 pin connector, the unit should power, if not, then there is a problem.

Looking at Luinoz connector and the pinout definition for the Murano, they definitely sent you the wrong wiring harness or miswired it.
No wonder the unit is not powering with just your 20 pin connector, it is because it is missing ACC.



If you see the red wire which is ACC, it is absent on your 20 pin connector.
On yours, they are using IGN (Ignition on the 40 Pin connector) instead; red wire absent on Luinoz connector.


Not 100% sure if this is the only issue causing your car not to power on.


You can try to solve the issue by rewiring the connectors, but not sure how comfortable you are with soldering and moving wires around. I would just tell them the issue and tell them to send you the correct harness.


If you have the Bose system, send them the wiring definition for both the 20 pin and 40 pins connectors so they can get it right (found in AV.PDF).

 

[Chauncy]

Do you have any gaps between the Headunit and the dash?

Here is the video of my unit with Nova Launcher Prime set as the default launcher. Thanks again to Luinoz for the info regarding the cameras.

Yes, Canny7 is a perfect device both for exploring CAN bus messages and solving tasks like steering wheel keys decoding and (definitlly), can bus decoder sent in android head units is made using similar hardware. And I really enjoyed with original CannyLab environment with very basic "programming" level it implements

And you are right, searching for CAN ID & data meaning is a bit tricky task. As I said before, the original implementation was made by Yuri (nickname is unk521) on Russian Club Murano forum and he made a great job identifying this data.

Some CAN bus messages are generic for Nissan (e.g. ACC state, lever state, speed…) and you may google it in a minutes while other (sonar state and AVM control messages) should be studied thoroughly.
As for “managing head unit”: this task is much easier than you think. All work is almost done by AVM module: it reconstructs video from 4 cameras and impose sensors state and visual warnings on it and sends ready-to-display video with all green/yellow frames and icons on. Two things should be done only:

• say “hey, you need to show video now!” to head unit by setting “rear shift” signal to high and
• send AVM command to switch next view mode (bird view / left view / rear view in “R” and bird view / left view / off in “P”,”N”,”D” and “M”).

Sounds good, I will email them and see if I can get the right one sent over. In the meantime I’ll probably try my had at a little rewiring too, always good to learn new skills! Maybe I’ll get it figured out before they can deliver a new one!

 

[Luinoz]

I don't see a red wire on your 20 pin for ACC. Do you have one on pin 3 of the head unit? If it is a different color it should go on pin 7 of 20 pin connector.
