From what I understand, not only do you have to purchase the front camera, but also you will need an update to the computer to let it know you have the front camera.
My '19 came with the infamous trailer tow package also. Its not that big of a deal for me to not have the 360 view, I think after driving for 40+ years, I can pull into a parking spot without hitting anything.. but like most people, it seems odd that they pulled it off, just to put tow mirrors on.
I think I'm going to buy the standard power fold mirrors from infotainment.com... those will include a computer update to let the system know that you have power folds... but no built in camera.
