Anytime Front & Rear Camera on OEM Touchscreen Headunit?

I did a '14 touchscreen radio in my '11. It currently has the back up camera in the rear view mirror and I plan on leaving the camera there.

I would like to add a camera(s) to the '14 touch screen head unit.

Ive got the rear camera to head unit sorted out I believe, but I would would like to go a step further and add a front camera.

I want to be able to control both cameras anytime - for trail/parking purposes - but still have the rear camera come on as the default any time the truck is in reverse.


Iv found a DIY on how to accomplish this with 2 switches -



- anytime switch & a front/rear switch, but I really dont want to add 2 switches if I can control this with a single switch.

I believe this diagram does what I want -



Im not seeing it though?

 

I did some thinking and came up with this...



To me this makes sense. Controls the front and rear camera with a switch, and the rear camera turns on automatically when in reverse. Diodes keep the current from back tracking.

 

Bueller?

Im kickin around the idea of adding a parking/proximity sensor to the front bumper and somehow incorporating it into the front camera to turn it on when the front bumper is within X"/X' of something.....

If I can find parking sensors that work how I want.

I just installed mine but I did it a little differently. I used a wireless transmitter/receiver setup. Nice to have front view now.

 

This crutchfield https://www.crutchfield.com/p_21290...VWEsNCh1eDwinEAkYBiABEgK82PD_BwE#&gid=1&pid=1 gizmo looks like it would work. If you use one side camera input for the front and an rca splitter on the rear camera signal to the other side camera and rear camera inputs it should give you anytime rear or front while prioritizing normal reverse operation.

 

Any results on this?
