I have sirius in my car and wanted it in my shop so bought a home kit through Amazon . The first one would not power up the radio head, nor would the second one. I know the radio head works as it is the one from my car. If I plug it into the power cord it will light up but if I plug it into the docking station I get nothing, no lights. The third one is on its way but I am wondering now if I am overlooking something? Thanks in advance for any help.
