HYUNDAI ELANTRA BACK UP CAMERA

I'm Trying To Install A Backup Camera; What Color Is The Trigger/reverse Wire In The Taillight?

Hi I Saw A Sign Of Check. It Look Likes A Camera.I Dont Know Wht It Means. Can You Tell Me What Is The Problem?

Do You Think This Is A Camera Issue Or A Head Unit Issue? Camera Starts Fine Then Starts To Do This Or Go Back. Nav Screen Is Fine, Radio...
