Any updates? did you ever figure out how to sniff out the climate controll status?

It would be greate to combine this project with "ELM327 Bluetooth OBDII adapter with Leaf"

Not really any updates - Job changes convinced me to move to Seattle, meaning I had to prep my house for sale, pretty much every spare minute for a couple months went into that ... then just as I was about to move, an electrical storm put a power surge into the leaf and it's been having intermittent troubles since (currently at Bellevue dealership looking at a possible VCM failure)...

I'm nearly settled in here, so once the car gets back I'll hopefully have time to get back to the project.

As a note, with the brake/nav bypass kits available, I think all this could be done with absolutely no interfacing factory wires. The first thing I'll probably try to do is remove the few places I had to tap factory wires and use a bp kit for those interactions instead -- then get a bluetooth can reader connected and see if I can put together a centrafuse plugin to show energy consumption & climate control data. Centrafuse does strange things with the bluetooth stack, though, so I'm not certain it'll work as easily as it should. We'll see.

Let us know if you find a good source of the connectors. I really don't want to spend $175 for a bypass kit when all I want are the connectors.

would be great if you get it working ;)
One question. the rear view camera. after you changed from stock to a new screen, does the rear view camera work with the distance markers that turn with the steering wheel?

No - With the non-stock display, I get a good rear view image, but no display of turning guides.

I looked pretty hard for connectors for a while, and completely gave up, so I hold little hope for finding them outside of that bypass kit.

Meanwhile, got the car back :) Might try to get back into this project again this weekend, but I'm still unpacking at the moment! Plus, awesome new city, so much to do, and given how little of my time is actually spent in a car now, this is naturally pretty low priority...

okey. looking at the servicemanual, I understand there is more to it. so the turning guides are calculated in the stock lcd display. I'm guessing the static guides are also added inside the av-box?
The AV control unit receives the steering signal from the steering sensor via CAN communication and draws
a possible route line according to the steering angle.
• When the possible route lines are displayed, the side distance guide lines are displayed translucently.
• The possible route lines are not displayed when the steering is in the neutral position.
• The possible route line can be displayed/not displayed by selecting “Other Settings” - “Camera from the setting
function”.


Perhaps one could borrow some code from this project to get it working:
http://openxcplatform.com/projects/rearview-camera.html
combined with what we know of canbus:
https://docs.google.com/spreadsheet/ccc ... MUXc#gid=2

Do you have a link to the screen you bought?
when I search for it I do find some kits. Interesting if one puts a kit togheter with some lowcost,lowpowered arm device ;)
I'm looking at parrot screen at the moment for a possible replacement. however the android is v2 old, and there seems to be some issues at the moment.

Looking at the servicemanual on the tcu-unit. it looks like it's tied togheter to the av-unit. I did expect tcu(carwings) not working if one replaces the screen. however I'm a little curious on how the tcu-unit works. is it powered on all the time? I see in the servicemanual it is drawed up a cable from av-unit to tcu-unit marked usb-power. but I except the tcu-unit takes power from somewhere else where power is availeble all the time. am I right that the ev-bus is availble when the car is turned off? would be interesting to replace the tcu-unit with something else. perhaps arduino with canbus and gsm-module.

I have started gathering info on the connectors used, to see if I can buy the female connectors somewhere.

Connectors:
m83 - 20pin - steering switches and sound
m84 - 40pin - can bus, camera feed, mic, aux sound, park/reverse/speed -signal
m85 - 16pin - usb, u/d-voice
m86 - 4pin - usb
m306 - 2pin - gps antenna
m307 - 2pin - radio antenna
m312 - 1pin - satelite antenna

From the above overview, I will use m83, m84, m306, m307. I'm not sure what purpose m85,m86 is serving. Anybody knows? is m86 for the usb port right besides 12v socket?

Still on the lookout for the rest of the connectors.

Dear defiancecp


Do you finished your leaf NAV head modification?

I also want bring out original NAV because I want to get freedom from nissan service centre and manage car myself like I want.
Im ready to purchase car-PC but i need smart programmer to make this PC compatible with leaf.

no updates? curious. how hard would it be to simply move the MFD "into" the stock location cavity 1/2 to 3/4 of an inch?

I am using a 7" tablet as my head unit now (love it) and want to try and make it look more factory (right now just sitting on top of the MFD)

Hey there! I was just reading your thread on removing your head unit in your LEAF and I wondered about the GOM.

I noticed when I removed the head unit it went to "---" did yours come back to life without any issues? or did you have program something for it?
