Same thing happened to my truck. Dealership told me that it can cost up to 5000 dollars (canadian) worst case scenario and there's no guarantees. I ended up buying an aftermarket alpine stereo built for our trucks for 1500 bucks off eBay. ( brand new its 4500) Some people have had luck with unplugging and replugging in the connectors behind there glovebox to their hmi module or pulling the fuse for 20 minutes and plugging back in. Didnt work for me but it's a good place to start.
