Hi, all. Did anyone ever figure out how to get the reverse camera to work automatically without splicing into that wire near the peddles?

The original head unit accomplished this using one of the wires in the OEM harness, right? Would it be possible to feed the signal from that wire into the new unit?
You have to splice into the wire at the kick panel. There is no other way.

So is this possible for someone who has 0 experience whatsoever with this type of stuff? Not as far as removing the interior pieces and etc.

But changing the connectors and stuff? I want to give this a go, but seems like it takes an experienced and knowledgeable person to tackle this

In SoCal and willing to pay somebody to do this lol
You can't really mess anything up as long as you pay attention to what wires go where and have a basic understanding of circuits. I am in SoCal and have completed the swap if you need any help.

I've since completed my install and I did end up splicing the wire. Thanks for the reply though. And thanks to everyone else in the thread.

I'm having trouble getting power to the head unit. The radio fuse keeps blowing so I know I'm definitely doing something wrong. I'd be willing to pay you if you would be willing to help. I live in Chino not far from Orange.

I have a 2020 Civic LX that I bought about a month ago with a standard 5" display.
I really want to do this, but I would want someone to watch over so I can get this done the right way and have the standard functionality still available. Anyone in Minnesota / North Dakota / DFW area that I could get some help with?

Hi everyone – I've successfully retrofitted a Hondalink (ex and above radio) into my LX. It completely changes the driving experience, and it has been working great for the past 2 months or so. IF you are looking for an OEM retrofit, upgraded audio quality, and NO modifications to original wiring, this is for you. Having the Hondalink also allows you to customize the convenience features on the car (locks, lights etc) All in all, I believe I've spent a little over $200 in parts and a further $200 in tools and cables/accessories etc.

Following is a brief explanation of what you will need, I think this is best described as a 2 stage process: (i) Bluetooth, Android Auto & Apple Carplay, (ii) Adding AM & FM. Potentially, you can add-on LaneWatch, XM radio, Amp, digital cluster at a reasonable cost.

Worth noting there are variants and sub-models, ie. some equipment have native XM and HD radio, some have Nav,etc . I went for the barebones one, which is what you will see in the pictures below (no XM/HD no Nav/no Amp). I've not yet enabled the rearview camera (there is an extra wire which needs to be connected at the interior Fuse Box (have not yet found in which of the fuse box’s connectors to add).Further, steering wheel controls work perfectly (despite not having up/down function, which is present on the EX+)

As always, any modifications you do to your property is of your own responsibility, this tutorial is for information proposes.

1. Materials:
1.1- Basic Set-up (only native Bluetooth, USB connection, Android Auto and Apple CarPlay):
• 1 - “Tablet” - ~$700 New;~30 to 100 Ebay; part no 39710-TBA-305
• 2- Head UnitBrains - ~1200 New ~150 to 250 Ebay; part nos 39101-TBA-A21 (barebones No HD/XM and no Nav), 39101-TBA-A31 (HD/XM), 39101-TBC-A71 (Fully Loaded)
• 3- GPS Antenna - $15 - part no 39835-TBA-A01 (alternative google Honda GPS antenna)
• 4 (Optional)- Secondary USB - $30 - part no 39114-TBA-305
• 5 - Blue connector-Harness from “tablet to Brain” (often is included when you buy either #1 or #2) - $25 - part no39725-TBA-A01

1.2-Adding AM/FM module Set-up:
• 1 - Tuner - $80 - part no 39800-TBA-A11(AM/FM) or 39800-TBA-A21 (AM/FM/XM radio)
• 2 -Small Male Antenna Connector x2 - $10 - part no Mobilistics adapter for 2016 Civic
• 3 -Single Male Antenna Connector - $10 - part no39835-TBA-A01
• 4 - Double Male Antenna Connector - $10 - part no METRA 40-HD22
• 5 - Motorola-style M-M Connector x2 - $5

1.3-Additional parts, tools, and connectors:
- $10 per day to access the Honda diagrams and specifications https://techinfo.honda.com/rjanisis/logon.aspx

- On ebay, buy connectors and harnesses for Hondas (anything from 2010 onwards are reasonably similar, independent of the model, as the specifications are very similar). This will allow you to customize the connectors and have a solid mechanical OEM Fit. Also, this will serve to re-use OEM-quality cables and terminals.

- On amazon, buy a 635 pcs Dupont Connector, M-M, M-F and F-F Dupont (same as used for Arduino). This kit comes with wiring, solderless male and female terminals and different housings b/w 1 and 10 pins. These are sufficient caliber to conduct the amperage and have a decent grip to the connectors.

2. Bench Procedure:
This portion will be all about creating the additional wiring harness, which basically consists of 3: (i) back of the radio 16 pin connector (aka E connector) (Required) (ii) tablet straight 5 pin connector (Required) (iii) AMFM module straight 10 pin (optional). Below are the diagrams:

2.1 16 pin E connector

2.2 Tablet Connector
uploadtabletconnector_zpsnbk6xeex.jpg

2.3 10 Pin AMFM module connector
upload%2010%20pin_zpsbxcwn8g8.jpg
Sorry if this seems like a dumb question.. I've never done this before. For the AM/FM module I'm having trouble finding #5 labeled the "Motorola-style M-M Connector". Can anyone help me find it? It seems like thats the only one I'm not having any luck with. Thanks in advance.

So after you put the new head unit in, does the factory backup camera still work?

Hi guys!

So I did everything by instructions on 1st and 2nd pages and everything works fine. Except one question: I don’t have Sound. Even when I tap on sound bar (or on wheel) I don’t even get any notifications on screen about sound changing. Any advice about it? Also wheel buttons are working (at least change track)

I don’t have tuner, AM/FM module installed, could it be reason? I did all instructions for not installing AM/FM.

Also, any advice how to get camera working on rear mode?

Just made a new thought: my HU model is 39101-TFK-G72-M1. Maybe it has external amplifier? If so, could you please share with me part no I need to buy to get things working? And also need an advice: is it easier to buy amplifier or should I just buy HU with internal one?

I think its easier to get one with the built in. Less wires and simple.

If your HU has the double "antenna plug" in the middle it requires the external amp.
This photo is upside down but it's fine to understand.

This uses SPDIF2 for the amplifier.
The built in model does not have it.

In this case you need the external AMP or change the HU for one that does not requires the amp.

I have a 17 Civic LX I'm retrofitting with a 2019 Civic SI head unit. After getting the necessary parts I think im ready to install. My only question is the rearview cameras issue. I compared the LX wiring and SI/EX wiring. In the 24p connector of the LX, space 23 had a red wire going into it. Red is for models without the ACC (adaptive cruise control...I think) diode. Is there a chance space 23 could either be tapped and ran to space 15 of 32p SI/EX connector to get the rearview camera to work. This would mean no tapping of the light green wire at the fuse panel. Or am I completely missing something. The LX camera worked before the retrofit and this is the only wire not accounted for in the SI/EX wiring. Thanks.
