I have Sirius radio for about a month and tune to it through 88.3. Problem is 88.3 is an actual station in my city so sirius and local radio constantly "fight" with each other. I've tried to find another station to tune in with but no others will pick up Sirius. I'm using the Audiovox PNP-2. Is this a problem with the installation? Did the highschool kids at Best Buy screw me? Any help anyone can offer is greatly appreciated.
