Radio Station Changing on It's Own

[idreamofmazda]

I thought I read of post on this long ago, but my search found nothing. I had a second PCM update a few weeks ago in my 2004, fixed some of the transmission problems, and after a few days, the radio station had change on it’s own. I was making a turn at the time, and maybe I hit the up button on the steering wheel, but it didn’t jump to the next preset, just by one point. This has happened a few times since, while driving straight, and stopped at a light. It always jumps up, and not to a preset station, or any local frequencies.

I find it hard to believe that the computer is linked in anyway to the stereo. Any ideas?

Thanks

Loose tuner button/wire - since it seems to happen with motion?
