I acquired a 2010 Gen-3 Prius. I like the 2014 prius backup oem camera, and would like it to have a grid feature. I think the grid lines are driven by the position of the steering wheel. Example: Deepseek indicated the OEM system had this capability if navigation is installed and the lines would be static / automatically displayed while in revers. My 2010 has no lines when put into reverse. Is there a procedure to either activate or load software for said feature?
For 2010, grid lines were added by the Parking Assist ECU, if the car came with parking assist, which was an option in higher trims, separate from the navigation option. Without parking assist, the backup camera analog signal is wired directly to the nav unit, and the image is displayed without grid lines. In a car with parking assist, the backup camera wires go to the Parking Assist ECU, and it superimposes grid lines (based on data from the steering angle sensor), and sends the combined image digitally to the GVIF input on the back of the nav unit.
Do you have this switch on the dash? Do you have grid lines on the backup camera display? I think there's also a Toyota owners' site where you can supposedly enter your VIN and be told what trim and options the car had. I'd take that with a grain of salt, 'cause I put my VIN in and was told my car's a V, when it's very definitely a IV from birth....
