If you experience a 2023-2024 Toyota Tundra or Sequoia with no reverse lines on the screen like below then you will want to try this...

Gts+ go to circumference module utility and register whatever options the vehicle is equipped with on the cameras and stuff. After that, enter diag mode in radio unit thru nav module utility in gts+, function check, camera setting, view adjustment. Change all 4 camera views to 1 degree any direction. Complete adjustment. Restart vehicle and recheck if reverse guidelines should appear. Or if do everything listed above and then if that doesn’t bring the lines back tell the system that you replaced one of the cameras. That’s what it took to fix a Tundra that I had.
