And to be clear, I've had my Terrain for 5 years and this is the 1st time I've experienced this radio problem. I have SiriusXM and it's a 6 cylinder model.
1) Radio comes on when i start the car and then suddenly dies to a complete black screen. It doesn't respond to the on/off button. It might come back on within a few seconds or a few minutes or not at all.
2) Radio comes on at start up but the stations (favorites) do not show up nor does it show time, temperature or blue tooth connection. Then it might cycle like problem #1.
3) Radio comes on at start up but doesn't show temperature or time but shows radio favorites on bottom.
4) Radio screen goes completely black and doesn't come back in regardless of what buttons i push. Then input it in reverse and the backup camera appears but without the guide lines.
5) When some portion of the radio is on and input it in reverse, the guidelines appear ok.
6) Sometimes pushing the source or favorite key will wake the radio up from the dead. It might come back completely or like symptom #1 or #2.
7) Regardless of the state of the screen, it can go on and off whenever it feels like it.

I hope that this is enough diagnostic information for the GMC expert to look at this and get back with me on where to look for issues. Certainly I'm going to have to guide the dealer on solving the problem. As a side note, i spent 35 years in the computer industry and am entirely familiar with diagnostic techniques and problem troubleshooting in both hardware and software. Best i can tell there might be a cold solder joint or loose connection somewhere. Screen works ok so that's not the problem. Can i replace the radio electronics or is it integrated on some other component. Please help

Did you get the problem solved Cesar?
Does sound like a weak solder or a loose connection.

Angry 2012 GMC Terrain Display/Radio Dead

Well .. add me to the list. I have a 2012 Terrain SLE and my touch display, radio and back-up camera went dead. It started sporadically (turn off by itself/turn back on by itself a few minutes later) and then began happening more frequently (turn off by itself/turn back by itself on 20-30 minutes later), then finally turning off by itself and not coming back on. I have checked and replaced fuses, yet still nothing. I have completed numerous internet searches and am unable to find anything useful (outside of checking/replacing fuses). I am beyond frustrated. I would take it back to the dealership, but have had consistent crappy service from them that ended up needlessly costing me thousands of dollars and multiple unplanned days off from my job. Yes, I complained to GMC Customer Service about previous issues, and their "solution" was a service credit at the same dealership where the crappy service was done. Yes, there are other dealerships, but honestly, I am concerned that the other dealerships would provide crappy service as well.

Any and all assistance is greatly appreciated!

So, YES, I am actually replying to how this was rectified. Unfortunately no one else on this thread seems to have solved their problem OR are not willing to share it.
All pricing is Canadian Dollars

You can follow the dismantlement on Youtube Not my car but the same thing
It will give you a good idea on how to start out. The rest is fairly simple.

At any rate, I bought the body tools to help dismantle the centre console st CDN Tire for $34.50.
Dismantled the console. The tools helped as the first two panels to remove must be pulled back, to the rear, and not just popped out.
The rest is just being careful to get all the bolts and unsnap the wire connectors. The big connector on the radio must be unsnapped, lever pulled back and then pulled out.
Next sourced "used" radio from scrap yard. Very important to have the part number and code from your original radio, on the top of it, as this will enable you to get one that matches. The one I got was from a Buick Verano. As soon as i plugged it in the screen came back on but indicated the anti-theft program was activated. Cost for the radio was $379.42.
Now off to the GM garage to program the radio to my vehicle and options. Took all of 15 minutes for a cost of $25.28.
Everything works.
So total cost was just under $450cdn and i get to keep the tools. A lot less expensive than the close to $1,500 that the garage had quoted me to change it out.
OH! The scrap yard warrants the radio for one year. Same as if I had bought a refurbished one from GM.
