Reverse Grid Lines

Hi Guys & Gals,
Just installed a generic rear camera that comes pre installed on the number plate surround, I am sure you all know the one I mean. Is there a way of turning off the default grid that I assume is imposed on the picture? I notice it is no where near as accurate as the one that you can use via driver settings on the android unit but do not really want 2 grids showing as that will just confuse.

Some cameras have 2 loose wires that you can cut (1 to disable the grid lines and the other to use the camera as a front camera). What I was wondering though, if the Android head unit is not fully booted up, would you be able to see those Android grid lines? Are you able to reposition the lines on the unit settings?

Joying Remove Reverse Camera Mode

I have one of the latest Joying 2GB Sofia headunits, don't think it really matters which one.
What I do not have is a reversing camera and as I am not driving a bus or heavy goods vehicle I don't intend to get one.
So my questions are
1. Can change or tweak something so when I put the car in reverse the screen doesn't change (I know I could cut the reverse wire to the headunit but I like the feature which reduces the volume when reversing)
2. If the above is not possible is there a way to remove the reversing lines which show on the black screen when I am reversing? I am aware that there is an option for this but if I disable the revering lines in the settings I get a black screen with green text saying "no signal" when reversing.
Thanks

Test the wire, maybe is defective
FOr me works perfectly with Opel Joying 2gb

I have encountered the same issue. I do realize that if I leave the car in reverse long enough eventually there will be signal. The weathet has became cold I am not sure if there's anything to do with it

F-Cam app parking integration

Hi all
Bought an RCA front camera as I was hoping I could use the f-cam app to get front and rear camera views and to get the front camera on for 10 seconds after reverse as per the option for the front camera in the factory settings.
So had a pig of an afternoon running the cables and what not but the only way I get the front cam view on display is by the AVIn app which isn’t ideal as it kills the radio and also seems to stall and affect the head unit.
Selecting front in the fcam app shows a warning of missing input and if you set it to activate after reverse the same occurs.
It’s strange for the unit that have the option of this function without actually doing it via the video in feed, Do I need another harness for this specifically for cam input??.
Here is the back of my unit. Can’t do the soldering to the board mod, but hoping there’s an easier way considering it’s part of the operating system.

Isn't the front camera meant to be on usb?

Hi, only for dvr, I have that and it’s working well. But it doesn’t work with F-cam

Also noticed today that the rear f cam app is reversed ie left is right, but when reversing the view is correct. Can’t find any settings for the f-cam app.

Did you connected power to the RCA front camera? I do have a switch on my car to give/cut power to front camera itself.
If I don't power it up I get warning sign as well.

Hello! did you solve this problem? Im having the same issue

I have been spending the last week or two reading nearly everything in these android head unit forums. I have but one suggestion I cannot seem to find anyone who has tried it. I will be testing this method out shortly my self. But have you considered a 4 way video splitter. I have no experience with fcam app btw. Also I would mention that I have spent most of my time trying to find threads or posts of people who have used factory front/rear , 360 cameras for parking assistance. So far most seem to only use back up cameras or front camera for DVR(dashcam). American market brands of these types of splitters are 100-300$ usd aliexpress chinacom versions are 20-50$ I will be buying a china version when I get ready to order parts.

Was a solution ever found to this problem?
I am in same situation.
I have "fcam" app but it only shows reverse picture, can't workout which pins are for front camera so running front camera through AVin ....like above this is not ideal

Did you ever figure this out? Currently dealing with the same scenario.

I sorted it by buying a different head unit.. I now have a brosmartek 8227L and front camera works as it has its own input connection. It holds front camera image for 3, 5 or 8 seconds after forward gear is engaged after reverse

Hi to all,
I have the same problem and I found the solution..
So I found this diagram into the forum (https://forum.xda-developers.com/android-auto/android-head-units/vw-head-unit-android-10-t4132083)
As you can see there is an input for f-cam (No9) but if you see the plug (radio cable) the specific pin have no cable.
You must connect a cable for video with a new cable connected to pin No9 and you must also take the cround from another connection (I took it from No40) and with this two new cables you can creat a new female RCA for the F-Cam..
I hope my solution to help you...

Android 7.1.2 Head Unit - Screen Flipped upside down and reversed.

Hi, new to forum, looking for some help please.
I have a generic Android Head Unit for a Mercedes A150 which for some reason has flipped the screen upside down and reversed the screen so to touch the screen, you have to think opposite and upside down.
I have tried the Reversing X Camera Off/on setting in extras. No good. tried reset )push pin in hole). Still no joy.
Any ideas welcome.
I have images to post (and link to) but can't due to forum rules until 10 posts made.

Try the extra settings and change the reverse mirror see if that will fix it.

Whats the deal with movable reverse cam grid lines? Whats required?

Hi I have a PX3 based head unit and I'm wondering whats requried to enable the movable grid lines for reverse cam? I know that cars with ESP have steering angle sensor and thats whats used to move the lines, but what hardware/software is requried to make it work? With my current set up I only get the static reverse lines but I've seen Android head units which support this but not much is being said about how.
Any ideas?

You need a CANbus unit that decodes the sensor messages and a MCU firmware that knows what they mean or you can buy a backup camera with movable lines but those are not accurate for more than telling you the car is not moving in a straight line.
