How To Change, Adjust, Reset The Local Time On Nissan Elgrand E51 Clocks, (Series 2 With Navigation)

This is a description of how to change the time displayed on the clocks of the navigation equipped, Nissan Elgrand E51, Series 2.
I originally carried this out in September 2019 and posted onto the ElgrandOC forum, a write up with pictures, which is available here:
forum.elgrando...
A FEW WORDS OF CAUTION:
If you attempt this, it is at your own risk and I accept no responsibility for what you do, (It is easy to break the Nav Unit if you’re too heavy handed, (Hence the thumbs down! ) so maybe get your friendly Auto Electrician to help or carry this out?
It has also been reported that this method, may not work on the Series 1 or 3, E51 Elgrand.
I hope this info inspires you to give it a go 😁👍
All the best,
Elgrandonaut.

Огромное спасибо. В такой идеальной машине даже маленький недостаток как неправильные часы очень сильно раздражает. Обязательно сделаю все как у вас.

Спасибо за добрые слова и удачи Thanks for your kind words and good luck with your clock fix 😁👍

Ours was done yesterday - works a treat 👍👍👍

Well done Dai!

Great video. Must have taken you ages to modify it. A project for the weekend. Thank you for posting x

Did this today. Absolutely spot on. Genius. Thanks!

Fantastic! Well done Andrew 😁👍

@@andrewsmyth8615 Good Luck! You've just enough time to practice and find how long your boot up is to get it spot on? 🤞

[@Tesla4nz]

awesome!! finally have the correct time. Thank You!!

Thanks Adam! Well done for giving it a go! 😁👍

I just did this on a series 1 E51 - easy job for me, except for getting the Nav unit out not knowing how. PS; I used tin snips to cut out a section to de-solder the internal batt negative by levering out the middle batt pin.

[@5RGJDCoy]

Nice one! Well done!! 🤩👍

[@v6hilux]

@@5RGJDCoy after an hour, I went and checked time. It only displayed Self Test mode - 12:00, so to fix this, I needed to unplug power from Nav unit and then plug in again and it reverts to correct saved local time. We have no DST where we live, so a switch is not needed for internal batt, however, a NC switch/button will be needed for every start to get out of Self Test mode. At least that's better than Japan time being displayed.

[@5RGJDCoy]

Excellent!!

[@stueyquinn4803]

Would it cause problems for the car if i removed the sat nav unit completely?

[@stueyquinn4803]

@@5RGJDCoy many thanks for the information 👍

[@5RGJDCoy]

You would lose the Sat Nav display obviously, but also the Clock Display and the ability to lower and control the rear screen, plus the ability to split front and rear sound. Unfortunately quite a lot of functions go through the Nav Unit, including the CanBus signal. You could do it and see what functions you are OK managing without?

[@maniacm6]

Thank you, I will be trying that on a Juke

[@5RGJDCoy]

Good Luke Spyros, not sure it’s the same tho’?

[@maniacm6]

@@5RGJDCoy Thank you, not sure ether, frm outside it looks to work the same. We will see when I find the time to try. I am only worried if it lock when it looses power.

[@5RGJDCoy]

It might have a Nissan Anti Theft System microchip inside somewhere, that’s already programmed to your vehicle if it’s the original unit, so hopefully it will talk to the vehicle and be recognised on reconnecting?

Good to know! Well done and thanks Chris! 👍

[@jdee4763]

Great vid. Pity I don't feel competent to do this myself sadly Q"You're saving the GPS plug for something later you said, did you do anything with it?"

[@5RGJDCoy]

Thanks for that! 🤩👍 I tried to install a newer Nissan head unit but unfortunately the Nissan Anti Theft System NATS are a lot different and couldn't talk to each other unfortunately 🙄

[@rxstewart]

I reckon as a complete novice I could give this a bash but I would need more info on the actual parts / wires and connectors used? Any further info or links would be much appreciated. Also if I just disconnect the power would the time then just not show on the screens? 🤔 Thanks

[@5RGJDCoy]

Exactly Ryan, that would stop the clocks displaying, but the Nav unit is central to a lot of other functions because Canbus signals go through it. The easiest (and less involved) method would be to just snip the back up battery single leg, push the back up battery away towards the circuit board, then all you would need to get the Nav Unit and clock to reboot is unplug the unit, wait long enough for any residual current to dissipate (say 10 mins.) then reconnect as a practice, time your boot up (probably around 30 secs) and then re do just before 9am or 9pm, as for parts as a complete novice you're probably best getting an auto electrician to help. Hope this helps?

[@legopepsi]

Hi Elgrandonaut, looks like you have used a double pole single throw switch with 4 pins? Would like your feedback as I am wanting to attempt this on my series 2 :) Many thanks!

[@5RGJDCoy]

That's right! Two pins/one side for the back up battery and the others for the permanent battery connection (the 2 yellow/green wires that come into the back of the Nav unit.) You'll want to have the wire from the back up battery and the two yellow/green wires on the same side of the switch, so that when you 'close' the switch it 'makes' both of those connections respectively and breaks the connections when opened, so along with ignition off, you will cut all power to the Nav Unit. Good Luck! 🤩

[@legopepsi]

@@5RGJDCoy Thank you for replying and helping out the Elgrand community!! Hopefully I don't make a mess of it :))

[@5RGJDCoy]

Good Luck! 🤩 Take it slow and take photos as you go, to remember where things (especially the multiple small screws) live. 😁👍

[@user-wn1nh9mb2f]

Great video. Well done. I would like to ask you. Where do the red and orange wires connect? Does it power the NAVI C/U when the ignition and ACC mode are off? I'm interested in this because my watch stops when the GPS antenna is turned off and the ignition key is in the OFF position.

[@5RGJDCoy]

Thanks Dmitry, Yes it is the permanent battery power to the Navi unit that keeps its memory, when the ignition is off. The 2x Green/Yellow wires are interrupted by these wires and through the switch to be able to turn off the battery power, (Both Vehicle and back up batteries). The clock isn’t illuminated when the ignition is off. It should keep time tho’ Is yours a Series 1 or 2?
