The 09 Civic Si comes with XM built in. However I am a subscriber to Sirius, and have a sportster 5.
Now I know you can use an XM antenna for sirius, and vice verse provided you modify the antenna's plug to fit the respective receiver.
So I should be able to use the XM antenna built in the civic, and after some modification plug it in to the sirius, instead of routing an additional antenna outside the car?? yes?
So where are the wires found? in the back of the factory stereo or in a seperate unit within the car somewhere?
