Reversing Camera series 10. Some work and others don't why?

Good morning all,

I have a working reversing camera but it doesn't give a particularly wide view so I have been looking at others.

The one that I have that works is this one (170° Car Front/Rear View Reverse Parking Camera Waterproof Night Vision Camera):

I have tried two other ones, this (720P AHD Vehicle Rear View Reverse Camera 170 Degree Lens Night Vision Parking Assistance Camera CVBS Rear Camera HD Color Image):

and (AHD 1080P Reversing Camera, Rear View Camera 360° Rotatable Metal Housing Universal Reverse Camera for Car 170° Wide Angle IP69K Waterproof Night Vision):

I went for those as the video connector was the same (or close enough for the last one) so I expected the video to work but neither of these do, while the first one works fine.

The ends in the car are these:

The head unit is rather old by the looks of it:

and the back of it has the expected tangle of wires:

So this has more to do with video output types than anything else - is 'AHD' a new format that uses the same physical connectors or something?

Can anyone tell me what camera features I should be looking for, or maybe the head unit replacement journey is about to happen?

Any thoughts, cheers.

Paul
