I have XACT Stream Jockey w/Sirius Radion for auto and home with the boombox. No matter where I install the receiver I get the "Aquiring Signal" indication for about 5 minutes or more before it finds a signal. With the home boombox I have tried positioing the antenna in several place with the same result. When in the car I am getting the same and when first bought Stream Jockey, it was fine. Is there anything I can do to prevent this? Any help is appreciated.
