It's got that timeout value, where it will fully power itself down after the timeout in config.ini. So saying that software can't shut it down completely might not be 100 percent accurate. I don't know if that shutdown procedure is entirely controlled in the PIC or in the player code or in the kernel or some combination of the above...

The thing is, since it's a car-based device, Bitt's point is that it's gotta be able to gracefully deal with sudden catastrophic loss of power in order to be truly useful.
