I can't say definitively for a '14 model, but I'm about 99.9% sure it would require a major replacement of components and significant dollars due to the way Toyota integrates their audio/video systems (I'm sure that would be true on my '17). Amazon sells a portable Blu-ray player with a 1080 screen and an HDMI out (so it can display on other devices) for less then $200. Maybe not elegant, but I'm thinking it's the cheapest and easiest route.
