Hi guys any help connecting Toyota Highlander 2014 OEM backup camera to head unit will be good. I have been trying with 24 pins oem harmess but no luck. There are 6 wires pin #3,4 that's gray and blue also pin# 11,12,23 & 24 that's black,red,gray & white. Any help would be great. Head unit has Brake, reverse, cam power out, ground and female RCA. Thank in advance. Please someone help.
The first step is figuring out if the camera is just video out or if it is converted to something else. If it is just video then you need to find where and how you can tap into that and convert it to RCA. Then one of those pins should be a reverse signal, hopefully it is +12v on reverse but you should find out for sure or test with a multimeter. If it is +12v on reverse that connects to the reverse pin on the HU. If any of these turn out to be diferent post back here and I will try to help (unless someone more knowledgable knows more).

Sweeneyp is helping but still can't figure out. Did try what he said but HU is not displaying camera yet

Might end up installing aftermarket backup camera haven't figured out about OEM or might use DVR as backup for now
Is there any settings in software/ROM (Malaysk ROM) that need to be turned on as I'm not getting any power on POW CAMERA OUT when connect

There's no power out for the camera. Normally this taken from your +12 at your white back light. The same voltage is also
used to trigger reverse to the head unit if you don't have a specific wire under the dash.
Reverse cable is normally orange with a black stripe in your headunit loom.
So I connect reverse, brake, RCA, cam power out and grd to OEM harness and it should work right. I did but nothing look like it's working

Brake has nothing to do with this, leave it open for the time being, its for watching video. When you say cam power out where do you get that power from? For testing you could connect your camera RCA to the video input and select video in your head unit. If you get a picture, you do have power and video to your camera. If not, you don't have power or camera input or both.
I don't mean Cam input, which is Rear view camera normal input. I mean the video input in your loom.
Tried but no video. So what you think is wrong. But don't I need reverse to trigger video ?

If you're using Cam input you need reverse. But for testing if you use regular video input no reverse is needed. Just select
video input, AV input.
It's obvious that you are missing either power, video or both. In the schematics above, which one is yours?
Thanks everyone for your help got the camera working but it's too grainy not clear is that normal or do I need to tweak software settings. THANKS AGAIN.

There's nothing to tweak when it comes to Cam input. Grain normally happens in a low light situation.
Sorry it's not grainy but has horizontal lines, may it's not ground properly.

It could be noise, but also a resolution problem. i.e. PAL/NTSC. Are you feeding it with the right
voltage? I read something about 6 vs. 12 volt. If the converter is a buck converter, it will generate
noise. Try to feed it with a battery for testing.
Usually Toyota cameras runs on a 6V current, whereas most aftermarket units are on 12V. So you might need to put a volt regulator. More details here: https://www.toyotanation.com/forum/...tory-rear-view-camera-aftermarket-stereo.html
Hi,
I'm new to this, i have an android HU and rear cam installed. Rear cam can only be viewed once you switch to reverse mode. Is there an application that will allow you to view your rear cam even if you are not on reverse mode?
Many thanks for your help.

You have to connect power to the camera so it is powered up all the time. In addition, you will need a video splitter to share the camera's input with the head unit default input and another AVI camera input supported by your stereo.
Then you can switch the AVI input on to see what's going on behind you. This will most likely silence anything playing on your stereo while you're watching the rear camera, but it should let you see what's behind you while you're driving.

i actually had this installed and making any changes in the wiring is something that is beyond my capability, is there an app that will allow you to do it? thank you so much for your help markmorto;73145228
No app (that I know if) will control power to the camera. The issue here depends on how the camera is already powered up. The usual method is to get power from the reverse lights, or the head unit, and only power the camera on when you need to use it. You need to know how it's getting its power first.

You can just use na USB DVR camera.
Is there any app for reverse camera Settings? I have Chinese android panel and it's reverse camera settings appeared once or twice initially and now they don't appear to manipulate. Plz help.

So I am trying to figure out how to turn on my back up cam from my head unit, a PX5 GS running the Malaysk Rom. I came across this video https://www.youtube.com/watch?v=cvDfev5Cv-A. I have Nova launcher prime but I do not get the TW app in the nova launcher activities widget section. The back up came work when putting it in reverse but if I go into Avin or Fcam I just get a blank screen. I have a can bus adapter wired to the head unit. I know I can run a switch if need be but I am trying to avoid that if I can. I got my power from my reverse lights, not sure if that is part of the problem or not. I am hoping someone can help me out.
If your camera is being powered by the reverse light circuit then that's your fist problem. You need to power it with an acc or ign circuit. After that, I would just use a composite (rca) "y" adaptor and split the camera signal to your back up camera input and a/v in. But keep in mind, your deck will still need a reverse trigger (I assume your canbus will still provide this?)
Thank you, I thought if it had 12v ignition it would command the camera on. I am trying to do it with software like in the video.
You cannot do it with software, if your camera is powered by reverse lights.
You've better check that first, this is the most likely reason for blank screen

"nova launcher" trick works for my head unit too "Joying JY-JO002N4 SC9853i",
only with different activity from that video.
finally I have reverse camera on demand.
next step would be to replace this chrysler trash "canbus" garbage and put a normal universal audio speakers with amplifier and all rca connectors.
I got a weird problem. It's a pumpkin headunit that can with the car I got. It's been working fine ever since I've gotten it. But last night when I was driving the music stopped playing and the rear view camera came on the display while i was on the freeway. Clearly I was not in reverse as I was going forward. It seems like it was doing it when I was just going forward, until I came to a stop then it'll go back to playing music, but then once I got going again it'll display the rear camera on the unit. I wouldn't mind if it kept the music going. None of the buttons are responsive when it is in rear camera view mode.
I've tried a factory reset, it is still doing it. Even today when I the car was not on. I was just setting the radio presets again, low and behold the rear view camera came on but for a few seconds and went away. It is still doing it when the car was off. I'm kind of confused as what the problem is.
Is autopumpkin.com working for anyone also? It doesn't seem like they are in business anymore?
Thanks for reading, and any possible places to look.
Hi, any progres? I have https://s.click.aliexpress.com/e/DtwdJIt its px5, Mtce_gs_v2.90c. Now I have a little problem with rear camera. I bought reverse camera and tried to connect it into front camera input(I was curious how it would look like) and since then its stuck on camera view. Even after disconnecting camera. Only solution was disable "prohibit reverse" in factory settings menu, but with "prohibit reverse" disabled is obviously not showing reverse camera when I gear the reverse down. Everything is shown in this video. https://photos.app.goo.gl/XbYUHApzT8qTezkq6
Turns out it was the canbus decoder that has gone haywire. It reads the canbus and checks for the reverse message and turns on the camera. With it unplugged I do not get random rear camera view anymore, but I also lose my steering wheel button to control the unit. I'll see if pumpkin will help me out, my unit is out of warranty.
SO I'm sitting her pulling my hair out trying to figure out why I can't get a reverse camera to work. I have a 2013 WRX STi with a Dasaita TDA7850 MAX6. I have everything wired up and working except for the reverse camera. I believe the camera is an aftermarket one from the previous owner. The cables coming from the reverse camera are Yellow RCA, Red power, and black ground. The ground is ..well grounded and the RCA is plugged into the CAM VIN RCA input on the head unit. When I plug the power into a 12v source I can manually view the camera so I know it is receiving power and working.
I have also run a wire from the reverse lights and plugged it into the wire labeled "Reverse" on the head unit(pin number 2). But no matter what happens the head unit won't automatically switch to the feed.
I have also tried doing a 3-way connection between the head unit reverse wire, power wire for the camera, and reverse light wire. This setup turns the camera off when reverse is not on but still won't auto-switch to the reverse camera when the car is put in gear.
I am not against buying a different reverse camera because they're relatively cheap but I feel like the issue I am having is not related to the camera itself but either software or hardware on the head unit not detecting the 12v reverse wiring. I have verified with a multi-meter the reverse light wire provides ~11.8 volts when put in reverse.
Anyone with similar issues previously? Am I just missing a software setting or did I make a dumb mistake in the wiring?
There are settings for the reverse camera also in Factory settings menu.
Check there if reverse signal might be set to disabled.

Thank you SO much for pointing out what I should have already known. This fixed it!! The wording in the factory settings was some really bad double negative english.
