Weird radio behavior

My radio is always on so although I just noticed this it may have been going on for a while.
I can't change the stations or turn off the radio or change modes with either the touch screen or the steering wheel buttons unless I change the volume first. Once I do that I can turn it off or change stations with the steering wheel but not the touch screen.
Any ideas?

I don't have nav. I didn't try setup, just a minute. I will go check.
Well, you inadvertently solved my problem. I was trying everything and I hit the wrong button and called a friend and woke him up. So that part worked. He was nice about it. I was not able to hang up on him. I tried to hang up before his phone rang. I had to power down.

In the process I bumped something in the dark. I have always had a magnet clip to hold a piece of paper right above the radio. It has never been a problem. Some how it slipped down a bit and that is what caused my problem. If the magnet gets too close to or on top of the screen it disables some things.
