Hey again, guys.

Before I begin and you guys ask:
All the numbering is taking into consideration that the wires are faced towards you.
I repeat, the wires are facing you.
It's like you're facing the back of the plug, so to say.
Face the plug in order to view the wires as they go in.
I can't stress this enough.


Oh, and also, you WON'T need the BT-SWC-NI1 or similar adapter.
If you've read other tutorials and seen an image floating around, you'll see the numbering is different.
That is because that adapter plugs into the harness and obviously it needs to be flipped.

Don't worry, this numbering IS correct so long as...

Face the plug in order to view the wires as they go in.

Did I say that before?




Moving on...


So, I previously posted a thread only on how to bypass OEM Bluetooth and use the OEM microphone with the aftermarket Head Unit, but the image itself had an error and I decided to correct it and go with a full cost-effective tutorial for keeping the parts that I'm sure most of you guys want.

Seeing that a store-bought adapter for anything can be really costly, I decided to go with this.

For this tutorial you guys I recommend that you guys have this:

01 - Wiring (local hardware store)
02 - Wire strip and cut tool (for the wires we are gonna put in, not the OEM ones - local hardware store)
03 - T-Taps and their plugs (for the OEM wires, so we don't have to cut anything - local hardware store)
04 - Soldering iron and solder (for soldering the wires to the MT3068 circuit board - check tutorial image and read below)
05 - Heatshrink tubing (to wrap the MT3068 after we're done - and for whatever you want to insulate)

06 - MT3068 Step-down (bought online, got 6 of them for €3)
07 - Mini-USB FEMALE to USB MALE Adapter (bought online for €2)

08 - Stripped MONO MALE Microphone Cable (local hardware store)
09 - Stripped RCA / COMPOSITE MALE Camera Cable (local hardware store)
10 - Stripped MALE AUX Cable (local hardware store)



So I opened this thread in order to allow you guys to:

Retain OEM Reverse Camera
Retain OEM Microphone
Retain OEM USB Port
Retain OEM AUX / iPod Port
Bypass OEM Bluetooth (so you can use your aftermarket BT)
Know where the antenna wires are (in case you don't want to buy an adapter)
Know where the GPS wire are (in case you want to do some modding)

This will also allow you to keep your Bluetooth / Call Button on your steering wheel if your aftermarket unit came with the adapter or if you have one.


This tutorial probably will work for everybody, you just gotta figure out which wiring is yours and download the appropriate service manual.
Mine, despite being a 2015 Juke, had the connections found on the 2016 Juke Service Manual.
How did I figure this out?
I disassembled the unit and checked the connectors.
Granted, there were a couple of wires that had different coloring, but the numbering is what I went with.

Hope you guys find this useful.

Let me know what you think.


Best regards,
Bruno.

I'm curious why you're using the mt3068, it's a BOOST converter. If you're putting 12v IN you will have to have >12v OUT. Based on your drawing you are stating it's putting out 6v which is NOT how the converter works. You need a "buck" converter ie: LM2596

You are in fact right, @slumberbunny , I just had spare MT3068 lying around and that's what I figured it was.

It's been a while since I installed my HeadUnit.

I spent a whole lot of time setting up that picture and was really tired to use my brain.

Regardless, I DID point out the voltage, so there would be no mistakes.

+5v for the MIC and +6v for the Camera.

But thank you for pointing it out.

Will correct whenever I can.


Best regards,
Bruno.


EDIT:

For some reason, I can't edit the post anymore.

EDIT2:
Apparently there is a 1440 minute limit to editing the post.

Oh well.

Everything stays the same, it's just the chip that's different.

Regardless, you need a step-down and the voltages are as shown.

Or just use a USB car charger.
(BTW, the camera works fine with +5v).

Best regards,
Bruno.

Ok, here we go.
Super revised picture with even more info.

Maybe just print it out and keep it in your Juke?

Thank you guys for all you incentive and for having posted many things that helped me figure this out.
