No Infotainment, but Back up Camera Works?

[BigDubs]

Hey guys, first post here! The other night my truck barely started, and when it did it flashed a Stabilitrak error. I then I moved truck few feet out of my garage and turned it off. Went to fire back up 5 mins later and wouldn't turn over. I left it for a few mins and finally got it back running but my screen wouldn't turn on. No lights on my buttons either, can only operate stereo from the steering wheel controls.

 

Brought truck home and hooked up to the battery charger, left for 18 hours and then fired right up. Came home and didn't plug back onto charger, and the very next morning battery was completely dead. So I put a new battery in, all is good there, but my screen still won't work. I checked fuse 18 for my Radio, all is good there. Is there any other fuse it could be?

 

I have read about "HMI Modules" and that could be it. If so is it as easy as taking out and sending to a programmer with your VIN number?
