Bluetooth blanked out

Time for a new stereo? The Bluetooth in my 2016 TRD-OR LB (no JBL upgrade) recently crapped out (I've owned it since 2017). Settings page has the Bluetooth and Phone buttons blanked out, so I can't add/remove any devices. Unpaired the Taco from all mobile devices. The stereo also doesn't remember any stations after I turn off the truck. The head unit is original, never been modified and no work done around it that would've messed up the wiring. No offroading the last couple years, just towing and some commuting. Checked all relevant fuses and wiring inside the engine bay, but couldn't find any likely culprit. I tried the trick of holding the App button and turning the headlights on and off to bring up the special dos screen, but that also didn't work. Any other tips I should try before removing the head unit to make sure there's no gremlins inside the console?
