Auto-Trail Tracker fb 2015 how do I remove reverse camera cover to check wiring?

[Late Starting]

Reverse camera keeps going to a Blue Screen then a couple of days later it will work normally for a few times then do it again been doing this for a short while now thought it was about time it got looked at.
Also does anybody know where the wires run to get from camera to screen.
many thanks ln advance for all the great answers I hope to get..
