Modify system so the rear camera view is always displayed

[fciac]

Hello:

Has anyone modified the existing rear camera/touchscreen system so that the system is always displaying the camera's view (instead of just when reverse is selected) on a 2020 LT or similar?

Thanks in Advance

I've heard lots of folks mention they would like this, but no one has said they succeeded. My 22 with HD surround cameras lets you select the rear (or front) camera while driving, but will only display it for a few seconds. If you are stationary you can view any of the 4 cameras, but not the 5th camera that is in front of the rear view mirror that is for collision avoidance, adaptive cruise, LKA etc.

I was looking at the 2025 manual and I "think" I read that you can record front or rear camera. I'm unsure if that was the ICE or EV manual, I'm thinking EV. Time to trade up????

Ricklack - thanks for your time. Maybe I'll be the first one to crack this nut.

If you do I would love to know how you did it. Good luck!

Actually it’s easy. There are a lot of post about people changing out their reverse lights and the reverse screen not cutting off. If you change out the factory reverse light with a non canbuss bulb your reverse camera will always be triggered. Problem is you wont be able to switch back meaning changing songs or using your navigation won’t happen even when the car is off. In theory if you run a low voltage wire with a toggle to the reverse light you should be able to trigger it but that’s just a theory.

rawhite318: Thanks so much. This is exactly what i was hoping to do. I did look at other post regarding this but i can't find the wiring detail needed.
In your last sentence I'm assuming you meant to say "In theory... toggle to the camera (not to the reverse light). Is this correct? If it is, what voltage is needed to trigger the camera and what pin or color wire is it in the connector?
Thanks in Advance

This is the cable connecting my camera to the wiring harness. I'm unable to find a wiring schematic that would identify the trigger wire. Once I identify this wire my plan is to run power from the fuse box through a toggle switch (which i will located near the driver seat) and then to this connection point. The toggle sw will give me the flexibility to either have the backup camera operate as normal, or I'll be able to force it on no matter what gear is selected. So, if anyone has any suggestions on where i can find a schematic it would be appreciated.

Again this is for the rear camera on a 2020 LT.
