Hi, I just purchased a 2013 prius two a few days ago, and I would like to add a backup camera to it that connects to the existing screen. I purchased a toyota prius backup camera that came from a 2012 prius from ebay for $150. My question is, now that I have the vehicle and the camera, how do the two come together? Are all of the wires already present in the 2013 two, or do I need additional supplies? Is the harness there? I have read a few threads about installing after market cameras, and these threads seem to imply that the factory camera is simpler to install. I just can't seem to find any detailed information about this. Is it plug and play with the factory camera? Will any wires have to be cut? Will this void my warranty? Any information pertaining specifically to this camera and the 2013 two would be greatly appreciated. Thank you!
