Just replaced the camera/gimbal on my V2+. Purchased a replacement from ExpressRC through on Ebay (fortunately before they put the price through the ceiling). After much nail biting over how I would bind the new camera to my extender, I was relieved to find ExpressRC included a QR code to allow binding..then dismayed when it would not bind. Took me a couple of hours to realize I was barking (binding) up the wrong tree by trying to bind to a new code. The binding worked fine with my original QR code (on my old box). Lesson: If you buy a replacement gimbal/camera for the P2V+, just plug it in and it should work, no binding required.
