Thought about posting to the ongoing rear view camera thread, but this is a little different. Took the truck in yesterday for the rear camera recall. The old camera was bad from new, mid-July 2020, but the last 3 months + it has been flawless. Told the service writer that the old one worked fine, but he said it should be replaced anyway. With new camera installed, I noticed that the lines were not showing up, but figured when I had a minute I would go through the DIC menu to fix. Checked the 2020 Owner's Manual, page 120 says scroll through until you hit "Driver Assist", and the "Rear Park Aid" selection allows on/off for the guide lines. I have scrolled through the menus several time and cannot find a "Driver Assist" choice. I am pretty sure I am not doing something properly, but cannot figure it out. Anyone have a suggestion for me?
