Square box display in reverse

Does anyone know how to display square box in reverse on new tundra. It disappeared from me and I kind of miss that, it helped me out when backing up a lot. Played around with the settings but couldn't figure out how to get it back.

 

Ai is really getting outta control.

 

When you put it in reverse, there’s a little option box on the bottom corner. That’s the fastest way vs going through the vehicle settings

 

Tried that, the square thing did not come back...

 

Do you have PVM? Select the button at C


If not, need to press the button at B

 

I went out to the truck and Tried to fix it. Surprisingly it worked without me doing anything. So strange. Anyway, thank you all for your help

 

If your tailgate is not fully closed the guidelines don’t pop up fyi

 

Ah, I think that's what it was. Thank you so much
