13 sport back up camera help plz

[Jotec]

This is my first post. Just bought a second hand cx-5 i love it so far. I just put in a rear cam. But the infotainment doesnt switch to the cam when i put it in reverse. So i know the camera works and gets power.
I wired it in to the reverse power. When i put it in reverse and use diagnostic code 92 i can see an image. Was wiring into the reverse a mistake. Should the cam ger constant voltage? I only have video and the shield wired in to the factory head unit.

Thanks in advance for any wisdom,
Joe

I am unsure about constant power vs reverse power, however it sounds like you have to program the head unit to know that it has a rear view camera installed now?

Well, i hooked it up to the reverse light power supply so it only receives 12v when in reverse. Thanks for your insight but from what i have read it sounds like it should just switch to the camera.

What i am thinking is happening is the headunit is trying to sense the camera faster then the camera is able to receiving power and sending signal to the head unit. I would prefer not to use constant 12v so the camera isnt always receiving power but that maybe my only option.

What happened when you would put the car in reverse before the camera was installed? What would the screen show?

I would find a way to temp apply the 12v to the camera before activating reverse to try your theory. However it sounds like the factory video feed is 6v not 12v according to the below thread?

I know that when you add things like tom tom or the rotary commander you had to turn some of those features ON on the head unit in order to activate them. Like for instance maybe there is an option for the CAMERA VIDEO FEED to be activated when reverse is on.

Okay its installed and works well. Thanks for the tip and advice. I ended up installing it to the only constant 12v supply in the area which was rear wiper motor.
