Back-up camera not working Nd-bc8 with Avic6200 Nex


Recommended Posts

I just want to test to see if the camera is woking or not. The following wires that I hooked-up is listed below with the answer:Yes

 

 

red wire from camera to red wire from head unit. Yes

black wire from camera to black wire from head unit. Yes

rca wire from camera to rear view camera jack on head unit. (brown). Yes

reverse wire from head unit connected to back up light. No

 

Why isnt the image working even after i changed the camera view settings to ON?

Are you bench-testing the unit & camera, or is the unit installed in a car?

 

The camera's black goes to the common ground - typically a bolt in the chassis. The camera's red goes to a +12v source. The unit's red powers the unit (a switched +12v source). It does not power the camera. You could connect them both to the same +12v source.

Since you are attempting to use the camera view, the backup wire doesn't matter.

If you get no image, its could be a defective camera. Do you have any other way to display a composite NTSC video? A monitor or TV with a RCA video input? Just to test the camera.

I am bench testing the camera with my pioneer deck in the car hence why I want to see if a picture is showing up or not.  Are you saying I would need to hook-up the reverse wire from my HU and combined it with the RED pos in my HEAD UNIT for it to get power ?  (This is JUST for test ONLY)   I would eventually tap the reverse power wire to the reverse power lights underneath the fuse box (where I have located the wire to hook-it up without taping the "rear lights" which I heard isn't as clean install.

 

I have an Toyota Rav4 2003, I am using an aftermarket wired harness that easily connects to Toyota's wired harness via by color.  Now, I don't know FOR sure if the radio's wired harness black is specifically to ground but I can check the wiring in the manual.

Assuming your headunit is working (ignoring the camera issue) the adapter must be working.  Just leave that alone. It is important to eventually get the reverse sensor working - mainly to switch to rear view when you go into reverse. But that is a separate issue. It sounds like you have a handle on that.

 

For camera testing purposes,  ground the camera's black to some metal on the vehicle chassis.  Connect the RCA to the brown connection on the unit. Figure any easy way to run +12v wire to the camera's red. Even if it just goes from the battery. In fact, for testing, just put the camera under the hood (or wherever a RAV4's battery is located) and directly connect the camera's red and black to the battery. Then go to the head-unit and see if anything happens when your ignition switch is on ACC and go to camera view mode.

 

Does the long RCA cable that came with your camera have a loose red wire at both ends?  If so, that is just a convenience to make it easier to power the camera - not having to pull another wire from the head-unit to the camera's location. Use of it is optional. Some people just tap into the backup light power, but then they loose the ability to use the camera when driving. 

 

You could just splice the camera's red to the headunit's red. What I did was add a tap-a-fuse pigtail in my fuse box and power the camera from any switched fuse location. That doesn't mess with the existing harness (no splicing) and is easily removable. But either way works.

I did put the backup camera's red wire to the HU's red wire, but no image!  The camera itself is NOT defective nor the wires attached to it since I was able to test it using a AC/DC adapter with a old monitor I have at home.  My issue is why doesn't the camera just work in the car with backup cam's red wire  to aftermarket wired harness red wire to HU's red wire and backup cam's black to aftermarket wired harness's black to  black's HU?  THIS SHOULD show image of the camera correct?  Is the red wire enough to POWER the camera? IF the questions is correct it should work ..then the problem maybe that the black isn't grounded and therefore needs to be grounded.

The head-unit's black should be grounded. The camera's black should be grounded wherever convenient.  Don't just connect them together unless you add a ground point. If those red wires you are referring to are +12V (switched) then it will work. Somewhere in the settings of the head unit there is a Camera On setting. If the simple red/black camera wires are connected correctly, you should see an image. Otherwise, I've got no other ideas.

Ok, thank you for your time  I will check the ground connections and report back later!  And of course, I failed to tell you I am using those crappy T-TAP connectors on both the black wire and red wire on the aftermarket wired harness!  That could also be the problem, so I will use a butt  connector as a temp so isn't a connection issues associated with those t-tap connectors!  And yes the pioneer has a camera view on..I tried it and same thing..no image.
