Ok, next suggestion, I've also seen it where you press AM/FM or Tape/CD several times to cycle through until you reach the input option that isn't listed. Any chance this will work?

i.e. in our Toyota, pressing CD when it is already on CD goes to input "CD1" which is actually XM, which in our case has been replaced with an iPod input. (guessing you've tried all this, but it can't hurt to double-check)
