Want to hook up my Stiletto 100 Sirius radio and wondering if there is factory instaled antenna whith the plug somewhere,or I have to go with ugly stock piece from the package.Looked in the trunk but no luck

 

You should probably be able to use something like the "sharkfit adapter" from VAIStech to connect up your radio:

Though getting to the antenna adapter requires removing the passenger side panel inside the trunk. You should be able to use the instructions on this site for the IS XM radio install to understand the best way to actually do that.

 

Thanks for your help Jason.Have to wait a couple days for delivery.They have detailed instructions on the website (with pic).
