Hi Ruth, thank you for reaching out. This item does not have the dynamic guidelines that interact with the steering wheel. Kindly call our parts team at 1-866-529-0412 and provide the complete vehicle information. We'll be more than glad to help you look for the correct part. Have a nice day.

When I installed this camera in my 2016 Fusion, I got green lines to show where the wheels were pointed and white lines to show where they would go with the amount of steering input. I had these lines with the old camera before it stopped working at all.

Hi David, I'm pleased to assist you. Yes, it is possible to install a rearview camera or blindspot on a vehicle that did not originally come with one. You'll need a monitor (if your vehicle did not come with infotainment), wires, the fuse panel, or a switched power terminal, to provide power to the rearview camera.
