2012 Battery/Radio help

Hello everyone, I'm new here and come to you all seeking some help with a recent issue I've had with my 12' Tundra; specifically from the auto/truck electronics gurus on here. A little bit of background, at lunch the other day I went out to my truck(12' Tundra) to grab a bite and listen to the radio for a bit. Truck was off with key turned just so the radio would work. All of a sudden everything went black and the truck wouldn't start. Co-worker came and jumped the truck off and went to Interstate Battery and got a new battery for the truck(not 100% sure the old one was dead, but definitely didn't look good, it's possible that was the original battery, I know I haven't ever changed it and I bought it used in 14'). New battery in, truck starts fine and all is well for the rest of the week.
Last Friday the wife and I were loading up to go out of town, went to start the truck and she said something as I was turning the key so I stopped, and it seemingly killed everything...truck wouldn't start again. Disconnected the terminals and then reconnected and all seemed well and good. No problems all weekend, radio works fine, and had my phone connected and listened to music all day Sunday via aux with no issues whatsoever. Unfortunately, I'm looking to put the truck up for sale as I just got another vehicle, so was taking it to get a wash this afternoon and the radio went black and won't turn back on. Truck kept running fine, just the radio. Tried disconnecting the battery and reconnecting(just kept it disconnected for a few seconds), but that didn't work. Any suggestions from you guys would be helpful. Could it be something with the new battery? Radio and music when connect to my phone worked all weekend. Bluetooth still works.

TL/DR: replaced battery on truck...radio died/went black while driving today

Thanks in advance guys
