I had to bring it to the dealer, it took them a while to figure it out.
Turns out the MOST Fiber Pins coming out of the back of the Radio were pushed into the head unit. They were able to take the radio apart and push them back out. So now I know somehow the AVIN connector/splitter that plugs into the head unit with the MOST cable moved to it, somehow pushed the head units MOST connection in.

Been very frustrating, now it makes sense.

Picture included I hope this helps someone, if you know other places to post please do.

The way I got it in safely put the big connector into the head unit first without the MOST fiber. After you see the pins in the head unit are ok, carefully push the fiber into the new connector already inserted into the head unit.
