You were correct about the test mode (it was the right navigation key). When I tested all the other buttons they went from [1 0] when pushed down to [1 1] when you let up. The tuner button did nothing. It sounds like a problem with the hardware switch but I will try the firmware update as a last ditch effort. When I loaded up Monkey it says that my X3 already has the latest firmware. If I want it to reinstall it anyway, how do I do that if you don't mind me asking?
