Defaulting to Bluetooth Audio Player

So all of a sudden, when I turn my truck on and AUX is selected, I get the error " Bluetooth Audio Player not found." Aux is what my USB is playing on. But I have to hit AUX again to get rid of the error. If I choose CD or Radio, then I don't get the error, I only get it when I'm using the AUX button and turn the truck off. I did take the thumbdrive out and got the same error. I did a list of audio players and the system says there are none paired. So I'm not sure why all the sudden it's asking for one.

My local Toyota shop foreman says that's the way it works, but I've had the truck for years, and it just started this.

I made a video on Youtube to show my problem. https://www.youtube.com/watch?v=9aRJY_wox7I

I hope all this makes sense. If anyone can recreate what I'm doing and let me know if they experience 'no error' that'd be super helpful.
