I found an used Alpine TME-M750 monitor with brain in my garage. It's a 6.5" screen. Unfortunately it have a few scratch noted on the red circle because I had it inside the box and scratched against the brain. It comes with a mounting bracket as I recalled. I know I have it in the garage but need to search for it.
It have all the wirings

$120 SHIPPED.

 

Good pictures and a good post.Hope it sells for you..
