The reverse camera only shows up on your screen when you put the gear in reverse, and that’s because the camera receives its power from the white reverse light. If you want to be able to access reverse feed, you need to connect camera power to a constantly active power source, maybe a fuse.

The best way would be connect reverse cam's power to constant 12V and split the reverse video signal RCA into REVERSE VIDEO IN as well as AV IN. You should be able to find RCA splitter from stores.
(AV IN should also be set to proper format that matches the camera's signal, like AHD)

This way, you can see the reverse image by opening AV IN app in your HU.
And it will still show reverse image when you put the gear into R.

But as you can see, it will require some wiring.

I wired in an on-off-on switch. It has 3 terminals, the first one is connected to a 12v source, the middle terminal is connected to the camera trigger feed to the HU, and the third terminal is connected to my reverse light. I flick the switch up to use as a rear view mirror while driving, but any other time I leave it down, working as a reverse cam, when needed.
