Backup camera install

[jasonb0816]

I have a 2007 and added the factory radio with the lcd screen. I got a backup camera and tried connection with wires to the 4 prong outlet on the back on the radio. I followed with wiring from the 2014. I know different year but the plug is the same. Anyway I can not get the camera to display. I hooked the camera up to a display and it works great. My wiring to the radio seems to be off. Can anyone help with the 4 wires that go to the back of the head unit?

Thanks

What kind of camera? Is it the license plate style? Just did one of those on my 2012. Pictures or more info would be a great help.

The OEM camera is 6V vs the Aftermarket 12V, Will not work in that way
I recommend that you only connect to the radio the Video signal and take the voltage for the backup camera from the reverse light

I did something similar to my CX-7 2010

[kenny7821]

That is exactly how I did mine

Its an aftermarket camera that fits where the OEM one fit. I connected the reverse light to the camera then to the back of the radio. So the camera only comes on when its in reverse.
the 4 pin on the back of the radio was wired
VIDEO + ___ GROUND
VIDEO - ___ REVERSE LIGHT

KBEZON:
Are you saying to only hook up the video wires from the camera to the radio and not to connect the ground or the power. Then to ground the camera and tap it into the reverse wire for power?

If so where do the 2 video wires hook up to the factory DVD/Navigation player.

Thank you !!

[kbezon]

You have to connect the video and the signal ground of the camera too
the ones that you have to connect are the 12v for the camera power

All the video conector ( yellow) ( inside 2 wires goes to the system)
Due I swap my display into a Navigation monitor instead of the no camera, I welded the 2 video wires inside the Display ( an extension female video cable)

[jasonb0816]

Thanks. Still looking where the wired hook up n the back of the radio. Does anyone have the wiring diagram for the factory navigation player?

[kbezon]

The radio that has the video there is the one that has screen on the radio
the "regular radio" does not have any video input

you will have to solder the wires directly into the Message Center module for Backup camera ( I did in this way)

[jasonb0816]

This is the radio I have on my 2007. Looking to find the wiring diagram so I know where the wires from the camera go in the radio.

[jasonb0816]

here is the back of the radio

[jasonb0816]

Anyone?

[jasonb0816]

So I tried hooking up the camera and when in reverse I can use the video cable and see the image on my video camera when I hooked up the RCA. So I know the rear camera works.
I tried just connecting the video cable to the head unit and nothing. I ran a converter from the camera and reduced it to 6v then used the power and ground on the back of the radio and still nothing.
Please help!!

ok, the camera has to be plugged in to the radio (only for video) to the reverse light (under kick panel driver side), to the voltage (because OEM is 6v and aftermarket is 12v) and to the ground.

Are you using aftermarket cables to wire the camera or some sort of OEM wiring?

The cables need to be plugged in the back of the unit on the 4-pin connector (there's only one).

Let me know which cables are you using and i can guide you.

I am using an aftermarket camera. I found the reverse light wire at the back of the car and wired that to the camera. I used an OEM like 4 pin harness and plugged it into the back of the radio along with a 6v to 12v converter. The camera turns on when in reverse and I can hook up an external source and see the rear camera. Problem seems to be that the radio does not switch onto rear camera video when the car is put into reverse??
does the radio need to be programmed to know that is has a camera?

any help would be greatly appreciated

I installed something similar into my car. You need to plug the video RCA (i suppose that the radio has the adaptor) and the trigger (this one is important cause it send the signal to the radio that you put reverse)
So... you install the camera and plug the RCA to the radio adaptor and you have to find a wire that sends you 12V to the radio camera trigger.
In my case, the camera that i bought had the RCA and trigger in a same cable so i have to find a path to trace the cable from back to the front.

Hey guys I'm thinking of adding a back up camera to my speed 6 but I'm not sure which one to get and where I want to mount it. Anyone have any picture of where they mounted it? Also I'm looking at a few types what ones did people use?

Ok I think this is what I am missing. Do you know which wire on the back of the radio is the Trigger?

thanks

Is relative... it depends of the radio model that you bought, do you have a screen shot of the wire diagram of the radio conector? or maybe in the top of the radio theres some diagram?

The camera that you have to buy is the one for your model (search it for model and year and compare pictures with your plate light), normally you have to remove the light of your plate because the camera case has a LED light (see picture below)



Now... you need a radio that support that kind of camera, because the Mazda signal is not the same as RCA, so if you install that OEM kind of camera and you try to plug into a mazda radio it probably doesnt gonna work or you can burn something
