I have been researching this as well so I'll be following. I have the VL2 as well and know that if I power the camera off the reverse trigger wire it will flip on when I go into reverse as oem but if I power it constantly you have to go to the vline screen to view it. I would like to have a 3 way toggle switch that will allow me to turn on the camera while driving (using the vline screen) when pushed 1 way and to activate the front camera when pushed the other way. That is my plan of now. I'm just unsure on where to mount the 2 cameras.
