I have had Sirius for several years, had the old model Stratus and the other day the wiris rubbed through - it was going to cost 50 bux just to replace the wires so I figured I would go ahead and upgrade my radio. I got the Sportster 5 which is very cool, has live radio replay and rewind and ( cool factor ) you can change the colors - has about 16 different color combinations so you can match your dash lights, or mood, or whatever! anyways - my old Stratus worked well - had a little bit of static noise which I fixed by that little coiled wire you can buy off eBay for less than 20 bux. This new radio, I have hooked up the same as my old radio - and I hear shhhhhh sound in the background :grrrrrr: So I installed the FM antenna extender ( just a wire which mounts on the inside of the window and connest to the radio.... STILL hear the sssshhhh so I am thinking I am going to have to break down and pull out the stereo and connect the direct-connect to the Chevy radio and the Sirius radio. How difficult is it to remove the factory radio? Is there a link to a web page or step-by-step? thanks for the help!
