I'm not sure if this answers your question .. but I found this on ebay
My car didn't come with it. Does it come with the audio package? I do have Sirius 6-month because I have the 201A pacakge.
My problem is my sirius signal randomly cuts out for a couple seconds at a time, some times. I'm wondering if there is something wrong with my antenna, wiring, etc, or if it's just like that because it is only a free 6-month.
So if I buy this "sirius sharkfin antenna" will it improve my sirius signal?
more generally speaking, what can I do to boost my sirius signal in the car?
