the antena over the passenger is a dual antenna, xm and onstar. even if you didnt have xm from factory i think there is still a lead that is just hanging over the glove box area (where the airbag stuff is). you will probably be able to use that instead of adding a new one( i realize its already done, but you can remove your old one). but if it is there (the lead) you might have to midify it a bit, there are litle channels on the receiver plug and thing sticking out of the lead plug which you might have to cut or shave off. i think someone asked the same question somewhere else on this forum a bit ago.
