| IS XM available on 2006 DTS Lux. I
 I recently purchased a 2006 DTS Luxury I with AM/FM 6CD changer, but no XM. The radio has a "CAT" button and dashes on the preset buttons. Presumably it is "XM ready". What must I do to get XM service in the existing radio? I do not want an aftermarkete XM set up! All comments would be most appreciated. |
