Rearview Camera for E53 with OEM Navigation

[Maruzo]

Hi all, does anyone know what this looped white cable is used for from the product photo?

On the ones I have bought like that it disables the grid that shows on the screen aka distance lines when you cut it.

It should say what it does in the instructions.

Where did you find this? Is this plug and play for the oem mk4 navi?

Here's the ebay link for the camera: https://www.ebay.com/itm/Reverse-Bac...72.m2749.l2649

It should work since it looks almost identical to my first camera, which is also sourced on ebay: https://www.ebay.com/itm/Car-Camera-...72.m2749.l2649

The problem is, after connecting it, the screen just flickers like it has received a bad signal. The camera's image can barely be seen through the flickering images, so I know it's connected, but i don't know where i've done wrong!

Thanks Crowz, that helps a lot!

I'm trying to troubleshoot and figure out where i've gone wrong, or if I simply purchased a defective unit.

The camera is flickering images when i'm on reverse. The nav screen flickers and the backup image can barely be seen through the flickers.

I connected the camera using the following items:

I cannot see any power return for the camera power anywhere. The red and black wires (+12v and gnd) for the camera appear to only connect to the camera decoder (whatever that is - a switch?) but there is only a single wire feeding the decoder...

If you get any signal from the camera the power return must be coming from the video cable and this could make for a very unstable picture.

Did the decoder come with the camera or did you buy it separately?

Try connecting the black wire from the camera to a ground screw somewhere and see if the image improves.

Looking at this further, you must have run another pair or wires to the reverse light as well, which aren't shown on any of your images above, right? This is the source of power and return and it powers the camera AND the decoder? So the decoder needs power FROM the camera, not feeding power TO it...

Makes more sense... but doesn't explain your bad video..

I guess check your connections?

I had similar image on my backup camera using navicks module. Ended up needing a resistor.

That's because the 4.8iS uses PWM on the lighting circuits and you need to "rectify" the pulses to obtain a smooth DC power line. The earlier cars don't use PWM, so this doesn't apply.

Hi Wpoll,

Camera has a video cable and a power cable. The video cable has an additional wire besides the video feed. The power cable has + and - wire.

The way I wired the first camera was this:

video cable connects between the camera's video out to the cam video in on the av harness I purchased (see picture I posted earlier)

For the power cable, the positive wire is connected to the 12v wires from both sides of the backup light, as well as to the 12v on the switch box. The negative is connected to the negative from the switch box.

That's pretty much it. The camera works but due to a defect on the lens (mostly my doing), the image aren't sharp. So I purchased another thinking the wiring should be the same.

Anyway, that's where I'm at. I'll report back once I re-wire everything one more time to make sure I didn't miss anything.
