I have nice Honda JAZZ 3rd gen (GK5) with CVT, Navigation, Line watch camera, park-sensors, etc. EXCEPT of reverse (back up) camera.. First time my daughter draw my car - she told me that my car is SHIT, because it has no rear camera.. 🙂

Hm.. I’ve started to think what I can do to get it to my Honda JAZZ. Main idea was: I wanted to have rear camera view at my ORIGINAL Honda Multimedia display unit! No any bullshit with extra screen on dash board or change my original Honda OEM Multimedia unit to 3rd party one. All should be ORIGINAL or "work as ORIGINAL".. Official Honda dealer denied to modify my car and install new OEM camera.. 😡



So, I’ve start to collect information, schematics, read forums to be able to understand if it is possible to do upgrade and install back up camera to my Honda JAZZ. It was not clear at beginning if my original Honda Multimedia unit has been pre-programmed to be WITHOUT rear camera or not.. If YES - I had idea to buy from junk yard OEM Honda Multimedia WITH camera connected before and possibly to have some problems to pair it as a new unit (on CAN-bus).. Other possible way was to reprogram somehow my original Multimedia unit to get rear camera work. Last and easiest choice was just to connect new CCTV camera to my Multimedia and see if that will start to work.. Psitive hope gave me information form system diagnostic ( MENU + On/Off + Brightness ). I saw that REAR WIDE CAMERA exist at my Multimedia Unit but it is in Yellow color (not active / disabled)..





Inspired by <https://www.fitfreak.net/forums/3rd-...onda-jazz.html> @carlyee modification jobs at his JAZZ in Australia - I’ve decided I definitely should try as well and see what happens..


This tutorial gives you an IDEA how it can be done. It works 100% at least at Honda JAZZ GK5 (3rd gen 2015..2020) and similar Honda FIT (2015..2017) with 7” LCD multimedia display unit.


Information to know before to start to do any modifications:
- Original OEM Honda CAMERA is NOT standard 12v unit but 6v..! To install an original camera – it would take more efforts, more cables, extra connections and most important I would need to cut a hall in the trunk for new OEM camera.. Standard 12v CCTV camera from Aliexpress would go on top of back plate light unit and this camera would have one cable only..
- Honda OEM multimedia display has video of 720p resolution.
- OEM CCTV camera type is NTSC analog signal (not PAL, not digital AHD).



So, my choice had been made to use universal (standard) 12v camera from Aliexpress with following requirements:
- As better camera quality as possible (I’ve choose SONY SVBS with analog NTSC signal)
- Resolution NOT LESS than 720p (720p or higher)
- View angle: wide enough to see border shapes of the car. I have chosen camera with view angle 170° (180° angle makes strange, funny image, which I personally don’t like).
- To have new camera kit with as LESS connections as possible (RCA video plugs, power plugs, etc.). Every connection reduce HIGH FREQUENCY CCTV video quality (reflection of high frequency signal at each connection), expose connections for oxidation, etc. All connections I’ve made hermetic by rubber tape (self-vulcanized tape). All solder points I’ve made hermetic by vanishing them (I’ve used for that wife’s nails paint 🙂 ) and few PVC tape layers on top of each connections.


I’ve chosen CVBS-720p (170°, GFA) camera with as less connectors as possible (RCA, power plugs in the camera cable harness). There are different choices on market. All depends on your preferences..




So, to make your Honda multimedia unit to show rear view image you HAVE to satisfy following conditions:

1. Multimedia Honda system should know that rear camera is EXISTS! It was the most difficult and tricky part to me to get to understand it and make it work.. Without it - all my efforts wasn’t been successful. You SHOULD simulate CAMERA_ADPT signal (C19 pin should have 0v (grounded, <0.2v)).
2. System should know WHEN to show CCTV image on multimedia screen.. Rear image at Multimedia Unit should be shown (triggered) during Reversing your car (Rear shift gear is enabled): to do that BACK_LT (C7 pin) should have “Battery voltage” (+12v). I’ve took +12v from wire harness of my Back Lamp (you can trace BRN wire from rear lamp to internal car wires harness and solder connection to this wire). This way of feeding/triggering +12v power gives you a bonus to keep camera energized during Reversing car ONLY (no need to keep your Rear camera powered and heat up all the times).
3. You need to SEND camera CCTV video signals (video + ground) to multimedia unit: Camera-Video (C15 pin, standard video signal: approx. 1.7v) and Camera-Video GND (C3 pin, shield of video cable).


My Multimedia display has 24-pin connector, which supposed to have all signals for rear (back up) camera.



To feed power to camera (as I’ve mentioned) I’ve used +12v from my Back Light lamp: BRN wire +12v, BLK wire 0v (GND). I’ve personally found the easier to solder my camera negative wire (GND) to the grounded point wires connection (located inside of car near to trunk), while +12v positive wire I’ve soldered on BRN wire harness (see schematics below..).

My original 24-pin female connector had two signals only: Pin-1 (RED: F-CAN L) and Pin-13 (WHT: F-CAN H):


Easiest way to connect all new required signals to Multimedia Unit – it is to make an adapter 24-pin Female<>Mail (MX34024SF1 <> MX34204PF1) and connect it between original cable-harness Female connector (showed above) to 24-pin Mail of your Multimedia unit. In this way you will avoid to do any modification on your existing original Honda wire harness connectors or damage it. One pair of M-F plugs (MX34024SF1 <> MX34204PF1) you can get for 4..7€ at Aliexpress.


Below is a drawing of C-24pin plug at Multimedia Unit, which shows you what pins you need to ADD (in BLU square) for new camera. Please keep in mind all signals are INPUTS to the Honda Multimedia Unit (except of ground wires obviously).


To have less wires at installation - I’ve took “0v” for CAMERA_ADPT (C19 pin) from Video signal C4 pin (CAMERA V GND). I’ve simply made a wire jumper from Multimedia plug side.



Below are schematics of original OEM rear camera installation. At BLU showed signals, we need to have (BACK LIGHT with brown colored wire):



Required signals to have video on the screen (C4 you can jump to C19):



So, at the end of you installation – as soon as you put your car to “Reverse” gear – rear camera gets +12v power and automatically pops up image of rear camera at your Multimedia Display unit! Simple as that !! 💪

As a guidance to show location I’ve took BACK LIGHT +12v signal from:



For manual gear car – same idea would be used:



During testing system and searching correct signals to get to work rear camera:



Last thing from my side: after installation, I personally didn’t like guidance lines from Camera (bottom colored) and Honda Multimedia unit (top one).. I remove them both from Multimedia image. Bottom colored lines you can remove from camera side (cut a jumper at camera to disable them) and top yellow lines you can disable from Multimedia unit by press MENU button and select Disable. I wanted to see a picture without any extra information and have more image details as possible. On top of that - by reversing the car to any obstruction your park sensors will start to beep AND that will be shown on bottom of the display as YELLOW or RED bar (depends how close you are to obstruction).









I hope my experience will be helpful for some of you. If you will have any questions or suggestions - don't hesitate to write it. Good luck !!


Some reference on video tutorial – how to remove and install interior of the car (to run CCTV cable) from HONDA geek (https://www.youtube.com/@HondaFit4Adventure):

 

Really nice work! You put in a lot of effort and it paid off.

 

Great work !

 

Impressive!

 

Hello,
thank you for your great explanation, but I have a question for you. My car is manual gear and I need +12V for camera supply. In the photo I highlighted the connector where I found the brown wire with +12v. Is this the right one please? Thanks in advance.

 

How does your 3rd Gen Jazz not have a rear backup camera?

 

That's ... a lotta work. I would have just cut my daughter off, disowned her from the family and refused to speak to her ever again for criticizing my car.

 

Dremland> Hi, Can you write model of car and year? I will check schematics.. Preliminary, based on my info I've put above - it should be BRN wires (as you have found) with pin numbers at plug/socket Q33 or N1. Is it corresponds to your interface plug? In the worst case - you can just test it by shift your manual gear to REAR and check if 12V appear at your BRN wire. If it is so - you can use this wire as 12v source.

Chitown Fit> For your information - Honda (Fit / Jazz) has different packages and rear camera I believe included by default only at Comfort edition.. You pay - you have or install it later by your self. By the way your answer to the guy is very informative..

 

Backup cameras only became mandatory in the US/Canada effective 2018. Before that they were optional. Different countries have different standards. OP lives in Lithuania where different standards may apply.

It's like running lights. Mandatory in Canada but not in the US.

 

Hi Whopper and thank you for your prompt answer!!
My Jazz is GK model year 2020 VIN is JHMGK3750... manual transmission
I followed your instructions and made the connector for the HU successfully. Now, to do a good job I thought, like you, to connect the power of the camera to the fuse box. I found voltage of 12 V when I engage reverse gear on the brown wire, but my doubt was that the section of the wire was too small ( even if the current consumption of the camera is only 90 mA). So I thought I had the connection wrong...
Did you connected the same wire?
Best regards.

Edit: Please, I'd like to know the name and the postion of the box connectors (A,B,D,E,F,G,H,J,M,N,Q,R,T) to find the right pins. I have a connection diagram for the US market (MITCHELL electrical testing&troubleshooting) that does not correspond to my box. Many thanks!

 

I Recently fitted a reversing camera to a RHD 2018 manual gearbox Jazz 1.3 using this guide.
I picked up the 12v supply from the under dash fuse box 7470-5635-0W using the brown wire with the silver markings. This seems to be in the same location as indicated in your picture.
I can’t find any schematics for the fuse box that indicate the connector IDs. But it is an end terminal
so could possibly be N1.
Hope this helps.

 

Hi Guys. I haven't take 12v of Reverse signal from any connectors near to Mutlimedia unit.



I've took 12v of reverse power from REVERSE RELAY (point of my connection to BRN wire is near to REAR LIGHT). There is BRN wire and it is not thin. Above are the pictures from different Honda Jazz/Fit car I've found in this forum. My SONY reverse camera had 12v power wire near to to camera and not from HU multimedia side. So, that's why I've took 12v from rear light of wire which supplies 12v power to it. Connect to the wire was easier for me - that's what I've done (solder and hermetise connection).

 

Many thanks guys!

 

Great write up and thanks to it, managed to hook up an aftermarket Android unit to the OEM camera, needing a 6v buck converter and shorting the "back lt" line from the oem connector to my Android unit.
Though on the OEM head unit, there seems to be some proximity sensor, which beeps when close to objects, am not sure if it's actual sensors or the OEM headunit making use of the video feed and processing it to determine when to Beep. With the Android Head unit i don't get this 'beeping' or proximity feature, so am wondering if there's some other connection I'm missing out or is something i need built in into the Android Head unit?

 

Hi Intosite. Close to object (front/rear) PROXimity sensors feels that and they give a signal to beep at multimedia display unit. I can try to find schematics for PROXimity sensors connections and I can attach them to this website channel. Please confirm that you need it. I have to spend some time to find it at my archives...

 

That would be great! Would definitely come in useful in helping me figure things out.


Just installed after market Android Head unit

 

I'm VERY sorry for delay from my side - just forgot reply to you (probably age..) So, there is a link to all possible and impossible schematics and documents for Honda-Jazz GK5 or Honda Fit GK/GP. There is no time to search for your specific page about park-tronics (PROX sensors wiring). Feel free to search and use yourself. If URL will not work - let me know.

https://disk.yandex.com/d/x-dFdUkTvQCYeQ

 

Hey thanks alot! I'm sure it'll be of some help. The beeping started working actually. I found some settings page to adjust those parking lines in my photo above, like the width, tilt and position, then it started beeping. I think it's triggered when things get close to the yellow and red zones in the image line. So it seems like it's software processed? The beeping audio doesn't sound like it's coming from the speakers as well but can't be certain

 

Hi. To get close to correct answer - please try to find original connection of park sensors (where are they connected to?). If they connected by schematics to multimedia - then it is 100% multimedia monitoring and gives you alarm by one tone at Low distance and other tone (continuous) at LowLow distance (at least that how it's work at OEM unit). I don't think your new Android multimedia alarms relaying on settings of your protection lines on the screen. Most probably it set by distance of sensing obstical, but I can be wrong. Please update with your info when you will figured it out. Also interesting to know how good is your new Android multimedia unit compare to OEM Honda device.

 

Thanks. The schematics look a little overwhelming, I tried digging through, Collision Avoidance and Parking Assist Systems files and Navigation system(looks like the OEM headunit), and I can't seem to find any mention of any proximity sensors. Though I see "Gauge Control Module" a few times around, and communications are CANBUS to the headunit. I also doubt the android head unit is doing realtime image processing, maybe its getting some sort of digital info from the CANBUS and using that in conjunction with my 'Parking Lines' settings, that's the only way I can explain how initial few days it wasn't beeping and finally started beeping today after i tweak the 'Lines' in the rear cam view.

For the head unit review, damn 12-13" is way too big, i was looking for a higher resolution in the 9"-10" size, it blocks the HVAC and redirects it to the windshield causing misting on the outside and having to use the wipers to clear it when it's humid outside. UI is not the best. Honestly I would not get this again, since installing I've found a 10" 2k resolution model, and am very tempted to replace this with it.

Compared to the OEM unit, mine is a 2018 unit, so it has the basic radio only. No android auto or anything. Only other time the head unit is useful is when reversing, other than that, almost never looked at. So any android auto is an upgrade, though my current android unit, the steering d-pad, source, menu and page buttons work, but i can't seem to get the 3 answer, hangup and talk buttons working.
