5. To be Sirius/AUX or XM compatible, the radio must be SW 43 or higher.
6. Turn radio off to exit.

The MODE button is not a good enough of an indicator to check if a radio is AUX or Sirius compatible. It needs to be manufactured 09/02 or later.
How do you find out SW version on business CD. Holding down my M button does nothing, apart from put it into Manual mode.
