Geeeezzzz feeling a little boneheaded as I did not get this from the manual. Appreciate you taking the time to point this out to me.
Appreciate ALL that have replied so fast and with such candor.
"After reading the install and user manual, the radio itself has the ability to display the camera two ways, one with the shifting into reverse when the wire is attached to the reverse lights and also on full time using the mode button on the radio to access the rear camera. you really don't need an additional switch to have the camera on anytime you want it."
