Hey guys, hopefully you all can help me out. I bought a 2014 mkz and not realizing after test driving 4 of them that the one i chosen didn't have a back up cam. So i went to this local place that installs back up cameras, radios, etc. He said that my car would need an interface installed into the current radio to make it happen one that is $300 that will allow the camera to work and another that is $500 that will allow me to add up to 4 cameras, built in navigation, allow me to use apps on my phone etc. Was trying to find the interface myself but having no luck. has anyone else run into this problem. I think the interface allows me to run sync 3
