I just installed an audiovox xpress (xm satellite) for my '05 av. Used the USA SPEC to direct connect to my factory h/u instead of using the fm modulator. I currently have the xm antenna mounted inside on windshield. The reception is very poor (sound quality is definitely not cd quality). I was wondering if its the location of the antenna (should i mount on outside of vehicle?) or if Sirius provides better sound quality. Even with the full strength signal on the xpress unit (all bars) i am still not impressed with the sound. ANy suggestions. Oh, i do have Onstar (dont know if that matters)
