Not trying to hi-jack the thread, but I have a 2012 GT/CS with the auto dimming mirror, are you saying the camera display should already be in that mirror and I "could" hook up a camera and it would/should work?
again, sorry about off topic but interested in this and you and GoT midlife CS
seem to be well informed.
