Well yes, as it happens.... :wink:MarshMA10 said:
I highly recommend this camera (the one im currently using)....

I also highly recommend using a power line filter from the reversing light to power the camera...

Here's my original video on how to install a camera. It shows it hooking up to the Android screen and with some aftermarket sensors, but you can delete what you don't need from it, as it shows the basics of what you need. It also shows using a relay with a separate feed, but you can dispense with that and use the filter instead (the filter smooths out the camera supply so you get a steady video image!)...

Hope that helps

Sorry for the thread resurrection. I have just installed a reversing cam, it kicks in and lights up the LEDs but black screen. I’ve just ordered a relay tonight as I figured it was low power supply; but will this power line filter sort my blank screen issues do you think? Much quicker/easier fitment so it would be preferable to a relay.
AnubisZed said:How is the camera powered at the moment? Is it directly from the reverse light?
A quick way to test it would be to run a feed directly from the battery and see, only as a test obviously. If that's successful then yes a filter
Yep, reverse light power only so I’m thinking it’s too low voltage coming through. I might just buy the filter as it’s £5 on Amazon, try that first and if it works then happy days, if not I have the relay arriving at the same time and can use that instead. Glad I found this post, could save me some faff if the filter works!
No I haven't, and mine had been in for a few years nowTBDL said:AnubisZed said:Sounds fair, best of luck and hopefully it works OK
Just a thought, the filter is not fused. I ordered a relay with built in fuse. Given the reverse light is fused anyway I guess I’m fine, but would you fit an inline fuse on the filter too for good measure?
AnubisZed said:Sounds fair, best of luck and hopefully it works OK
The £5 gamble did not pay off, unfortunately. I tried direct off the battery and the camera works fine, must just be too low voltage drawn from the reverse light. Job for the weekend to solder in a relay and provide the camera with direct battery power instead.
AnubisZed said:It's probably trying to draw too much with the infrared lights as well :?
So a 12v supply to your new relay and switched by the reverse light, as I did originally in my video
EDIT** That's pin 6 on the rear light plug!!
I’m totally stumped. I’ve wired in the relay. Ammeter confirms it’s getting 12v. Put the car in reverse and trigger wire is working as Ammeter confirms 12v coming out towards the camera, I ended up probing the actual wires I soldered on just to make sure ground and live are getting good connection. I wired in the volt stabilising box in line from the relay to the cam at first, removed it when no luck, but still no luck.
The lights on the camera light up when I put the car in reverse, so there is definitely some voltage of power getting to it, presumably the full 12v I measured further up the cable.
Putting in reverse also kicks in the camera on the head unit, so some kind of output must be going up the RCA cable to the MMI.
All the above, and still only a blank screen is seen.
When I connected the camera directly to the battery I had an image.
Any ideas? I’m totally lost what the issue could be.

Ok, stupid problem found. Putting it here in case anyone else reads this thread in need of help; my MMI had a front and rear RCA input, I had it plugged into the front by mistake. This is why it worked when I was testing as I had ‘camera’ selected. Still needed the relay for power, but I’ve wasted hours with this silly mistake.

Yes, all working great with no explosions, so I’m happy even with the wasted time on my own mistake!

Great! I found a really easy cable run for the RCA too, not one I’ve seen anyone else take in their videos yet; maybe for good reason, but it works for me and is a neat job. I’ll post up later with a video.
AnubisZed said:Sorry I didn't see this last night. As I was reading I'm thinking is it connected correctly, but as you've found it then well done
No worries at all, this was a school boy error and I recall now the RCA I left bundled behind the glove box a few months back had fallen out, so I put it back and taped the connectors. In this moment of future-proofing I clearly switched the RCA without realising
An interesting turn of events just occurred, I must have a wiring issue somewhere on the relay setup as the reverse light bulb is blowing, I replaced and then the next one is not lighting up (but doesn’t actually look blown). The only difference from before is the engine is running, whereas all my testing was with it off. I know the battery outputs a bit more, but no voltage should be making it to the bulb circuit as the relay outputs it to the camera (which is working fine). Camera is working fine, so the relay is doing its job, as is the trigger from the bulb.
According to my 12 year old there is also a loud high pitch noise constantly. I cannot hear it at all, but he can hear it the whole time. Must be the relay or some interference but I don’t see how by the rear cluster it could cause speaker interference.
I have the relay and the camera grounded to the reverse light/rear cluster ground. This is really the only point at which I could see something could interfere.
Any troubleshooting ideas for me? Can’t quite bring myself to remove all the trim and start looking tonight.
EDIT: diagram of how I’ve wired it
