can a dom's unit with a back up cam be wired to turn on with a switch as well as wired to reverse lights to automatically turn on.

to clarify, I want to know if the screen can switch to camera automatically when put in reverse but also be wired to a manual switch.

can it be done and are there any problems to look out like reverse lights coming on in drive when the switch is activated.

I tried searching for this but this question is way too specific.

 

get our NavTool unit, Made in USA, automatically switch to rear camera when in reverse and no additional connections required to watch rear camera in drive

simply connect camera to accessory power and use supplied push button to enable camera when in drive
