Roy being the great guy that he is replaced my dying X50 about a week ago. It was still under warranty. I would never expect something for nothing.
Well in any case it was getting a lot of the self cal messages and finally said service needed.
Let me tell yah, the new unit is FAR more sensitive then the old one was. It picks up PR and such at a much greater distance.
So the moral of the story is, if it's freaking out and under warranty..get it replaced. Just don't drive Roy nuts
