Can you explain how you are going to fit a 5” screen fit in a single din space? The bottom slot is partially blocked by the shift lever so a popout screen is going to be difficult to see and use, especially when backing up. I agree about doing it right but YOU seem concerned about saving money. I already have a pop out 7” screen that is perfect and disappears when parked.
The camera you have power bought is quite large if it is the same as Ricks and only a few infrared LEDs will be able to “see” through the slim opening in the cover - Rick cut a hole so the whole camera can see outside.
Randy, please fill out the rest of your profile so we’ll know more about you.
