Hi all, I have a 2012 Kia Soul 4U. It has an infinity stereo system and I'm changing it to a Pioneer AVH-4000NEX.

I'm wondering if there's a harness out there that will let me use the original backup camera that is already installed in my Soul. Or if not, is there a work-around where I can splice an RCA connector onto the camera wire and plug it into the head unit? Has any one done this? Will it work?

Depending on the connection type you may be able to find an adapter of some sort. I used the factory Sirius antenna on my 2010 Exclaim by using an adapter I found at Crutchfield.com when installing my Jensen VX7022.

Not seeing an adapter available, but on a 2012 the video signal is in the large connector closest to the side of the factory radio (Connector B). Video positive is pin #6 and Video negative is pin #18. Looks like it might also require a 3.3 Volt power supply to power the camera. Power positive on pin #7 and power negative is pin #23.

Thank you Drunken.Swagger. I think I can use this to splice into and plug into my aftermarket head unit. Can anyone give me some practical advice on how to do this? Or point me in the right direction?

You'll need a scrap RCA cable to make it happen.

Video+ to the center pin of an RCA
Video- to the outside

Try it and see if video appears when in reverse. If not then you'll need a 12V to 3.3V power supply (Shouldn't need more than 1 or amps of current) which are available on eBay or Amazon at a range of prices. Wire the 12V input to the red wire on your radio harness and the 3.3V output to pin #7 on the factory connector. Input ground to the black wire and output ground to pin 23.

Hey Drunken.Swagger, it didn't work. I hooked up everything like you said and when I go in reverse there's no picture. Triple-checked my connections. Hmmm... I know I can do this... I have to figure it out!

Any help is appreciated!

I'm having a hell of a time getting this working!

So I checked the voltage at the back of the car where the attachment goes to the camera. There is 3.4v for sure powering up the camera. I am not getting a picture. I am going to switch out the RCA connector this Saturday and see what happens. :-(

Just so you know what's happening... I have changed the setting on the radio and when I go into reverse the screen goes black but there's not picture from the camera.

In spite of this being a year old thread, I want to add to this discussion, because I searched high and low and could not find much information (or I should say, Incomplete information) regarding my particular Soul setup.
I have a 2012 Soul +, with UVO (infinity sound w/backup camera). It has a JBL amp with 2 connectors that I had a hard time finding pin out info on. The information I did find, was mostly for the standard head unit, and standard amp.
This all started when my battery failed. After replacing the battery, my head unit had no sound. Everything seemed to work, but no sound whatsoever. I suspected the amp, but had to find the correct pin out diagram to find the amp trigger to ensure it was even getting a signal to turn on.
After finding the amp turning ON, I realized my head unit was bad (Yes, of course I tried resetting it).
I went to Crutchfield and found a Pioneer head unit I liked (AVH-X4800BS), and they told me the Metra Axxess kits to purchase, for installing the new head unit and retain my factory amp, speakers, and wiring. I used the Metra #95-7349B dash kit, to install the Pioneer into the dash(no cutting or mods whatsoever). I used an Axxess HYBL-04 SPIDIF interface, and an ASWC-1 steering wheel interface. The HYBL-04 has a prewired plug to fit into the ASWC-1, so throw away the one that it comes with. You won't need it (you DO need the main ASWC-1 module). The HYBL-04 plugs into the 2 factory connectors that plugged into the back of my fried UVO head unit. You have to splice a few wires from the new head unit to the HYBL04 interface as well, but nothing difficult.
I didn't feel like searching for the E brake wire so I purchased a little brake bypass micro relay for $10, and used that for my brake wire. I followed Drunken Swaggers info regarding the camera pins. He has the correct pin outs, and I did NOT need a 3.3V DC adapter! I got one, but it would not work, and I used straight 12V accessory power to the camera power wire. I could not find any definitive specification on the factory Soul camera other than a stock number. Supposedly the Optima uses a 6V camera. I tried splicing the existing USB cable to a normal USB cable, but the head unit does not want to accept that (because it is part of that Aux/USB module in the dash, that is powered). The HYBL-04 claims to retain the Aux input, but I never use one and haven't tried it yet. (The pioneer has one on the back, I can plug a cable into if desired later). I ran the USB cord from theback of the new head unit into the little sunglass compartment above the unit, and plug my USB music in there. My sunglasses never fit in that thing anyway!
So, I am living proof that an aftermarket head unit can be attached to the factory amp/speakers/and backup camera. You have to splice an RCA jack into the wiring like Drunken Swagger said earlier, and this whole job was not fun or easy. But it can be done, and it sounds and looks good.
I'll try and attach some photos, as proof it really happened! I was gonna do a full write up on it, but got so frustrated, and took so long, I gave up. I just wanted to let anyone searching threads that it could be done and give the basic items I used to complete the job. The interface modules aren't cheap, and I spent just about $500 on all the bits from start to finish. P1060823.jpg P1060827.jpg P1060813.jpg P1060815.jpg P1060816.jpg

Just so everyone knows....All the wiring connections are done right there in the dash. I ran no additional wires back to the amp or camera. I did access the amp (back by the subwoofer) to test it's power, after the initail loss of sound, but nothing was altered. You need patience and a steady hand, and a soldering tool, and heat shrink tubing. I especially recommend the soldering and heat shrink on the RCA camera splice as those wires are rather fragile, and the heat shrink tubes really help protect your connections.
I found the best pin out diagrams (for my UVO infinity setup) on the Kia Optima and Forte forums. Most of the Soul diagrams I saw were wrong. Mostly, you don't need much info on the pins, as the Metra Axxess harness is just plug and play. Don't forget to turn up the potentiometer screw on the HYBL04 when you are all hooked up! I was pulling my hair out thinking I wired it wrong when I got done and had no sound!! I had turned the screw all the way to the left (counterclockwise) exactly as the instructions said to. They never told me I had to turn it back up to get sound! LOL!
Best thing to do is have a professional shop do it all for you. I'll let you know if I find a work around to use the existing USB plug, but at least I have Radio and CD/DVD player, and my iphone links in and USB thumb drives play music again. I have almost 97K miles now, so am not terribly upset with the factory head unit failure. I was ready for something new....

It may be an older thread, but many of us have this car. I just bought one and trolled ebay for the parts (I got a $300 harness with the spdif for $50) because i already owned a pioneer avh-4100nex that i wish to install since this year doesn't have android auto. I'm going to be attempting the install over the weekend.
Note that the local stereo shop told me the camera is 5v 3amp, but everything else i found says 6v.

as a follow-up to my earlier post, i looked at the pinout above and checked the voltage coming out of the UVO deck in my car and it is slightly over six volts. The 3.3v info is wrong or the non-amp system uses a different camera.
