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.

Well that would be cool if there is a lead their.

Anyone know for sure if I can remove that Acne Blemish and use the the lead from the OnStar /XM feed...??

I was having a problem with my puter when I tried to search this topic from the beginning. But it's working now.

I did find some info on this ....there is a XM feed wire off the OnStar antenna.. So now all I have to hope for is that the dealer didn't drill a hole to mount that black disc.

Not all of the warts GM uses for antennas have all the leads. If you have the wart with the little dingy antenna on top, most likely there is an XM lead (and the dealer should have known). Possibly there was no lead.

The little wart on the tri-mode antenna contains the XM and the Onstar GPS, and the little antenna sticking up from the wart is the cell antenna for Onstar.

I don't see no picture.
If there is a whine with the dealer installed XM, then they did something wrong.

Yeah ..your right back she goes....

Also.. would the dealer parts dept have the correct number for the GPS/Onstar/XM antena Wart ..? I'll order the correct unit in myself if the one I have is not right.
