Hi guys,

Did anyone ever try to upgrade the existing rear camera in the mazda 3 to the one used in Mazda 6 or CX5? The benefit would be to have dynamic lines while parking.

I know, that the camera with dynamic lines has 7 wires instead of 4 with static lines in M3 due to wheel angle sensor.
According to guides of CX-5 owners who equipped their car with 7 wire cameras, these cables go into the rbcm.
Would it be worth giving this a try?
We might use the same rbcm cable to connect the additional cables into.

After I managed to buy a cheap Mazda 6 camera, I did put in the new camera into my car:

Test of new camera

Unfortunately, I bought a Mazda 6 camera from the 2012 to 2015 model, which has a worse camera resolution than my original 2017 camera in the Mazda 3 BN. Therefore, I ordered the same camera from the 2016 Mazda 6 model.

For Mazda 3 BN Hatchback, there are two possible 7-wire cameras:

Mazda 6 Sedan 2012-2015 (GJ)
GHK1-67RC0
Mazda 6 Sedan 2016-2017 (GL)
GMC8-67RC0

As a minimum requirement, your car needs AFS or ALH, which means the car is able to measure the steering angle that will then be used in the 7-wired cam.
Please keep in mind that the resolution of the GJ-cam has a lower resolution.
The latest camera of Mazda 6 Sedan 2018 is not possible anymore due to being only a 4-wire camera with an additional ECU (?) for the reverse camera and four additional cams of the 360°-view.

In theory, you could do this change on the mazda 3 sedan as well, but you need the 7-wire camera of the CX-5 or mazda 6 wagon, but I am not 100% sure.

Didn't know the moving parking lanes camera required AFS or ALH, thought only a camera swap was enough.

So the one you used is:
Mazda 6 Sedan 2016-2017 (GL)
GMC8-67RC0 ?

How can you check if you car has AFS or ALH?

Have you any idea about the dimensions? I am curious if it fits the M3 HB (2014).

Is it plug and play or is there something more difficult to do?

I found both of the camera. Is the GMC8-67RC0 better or is it the same?

You need have 4 additional wires from RBCM to rear camera. Then you have to use the old camera mount and the new camera from Mazda 6 (Only 4 screws to change, very easy). Then connect 4 of the wires from the new camera to the 4 wires coming from the RBCM and the 3 remaining to the existing camera plug.

Main difference between the camera models is how the rear and front sensor is displayed (different layout with the red bars) You should stick to GHK1-67RC0.
I tested both cameras on my 2017 M3 BN and noticed this problem. I mixed the camera versions and had two different sensor layouts on my screen which was kind of annoying.

Due to this I have a spare GHK1-67RC0 camera available, if you are interested in buying it (sending a package from germany to the czech rep shouldn't be a big problem)

I have purchased the camera next day after I posted my previous comment. If haden't been so inpatient, I would have bought it from you.

I will advertise your camera here in our local groups. There are lots of mazda fans and I am sure they will be interested in the camera if they have the instructions which I can provide them if you help me. I sent you messages. I need the right wiring. I don't know where to wire the extra cables from camera. It is the only info I need to complete it. Please help.

@Baseraver, do you still have the GHK1-67RC0 camera? I am interested. Can you send it to France?
