And back on topic...mine doesn't have the centerline either.So I searched around the internet last night looking for picture and videos of the 12.1 in reverse. Not one of them I found had the centerline. I went to my dealer today and asked so we hopped in the only 4 trucks they had with the 12.1 in it. Not a single one of them had the centerline. I would love for the people who say they have to send a pic or video of the screen showing the 360 surround camera AND the backup cam with a centerline in it. Until I see actual proof of a 12.1 screen with a centerline, I'm not buying it.
