Just wondering if anbody else using the Sirius Jam Pack (the Audiovox unit) from Best Buy is having any issues with static and distortion in their installation. I bought it and had a local car audio shop install it but I'm having lots of problems with static. Don't know if it's from the wireless FM modulator or something else. Have any of you guys using the Sirius Audiovox setup had these types of issues? Don't know if maybe I should take it back to the shop to look at it or just buy something else.
