Hello all. I have a friend that has a 2013 RX that did not get the rear backup camera option. They want to add it but I'm not sure what options or prewiring exists to add the factory option. Does anyone know if the rear view mirror or the dash screen has the ability to take a camera input, or rather display a camera image?

 

I do not know, but you may want to see what the folks at www.toyotanation.com forum have to say. The Highlander is a twin to the RX.
