I have a 2009 clubman with factory Nav and Sirius radio that has lost the Sirius radio. When you put it on Satelite radio you get no sound and it just says acquiring at the bottom of the screen,.. I've tried all the things in the forums for those that have reported in and out lost of Sirius but this issue has gone on for 2 months without ever coming on.. any hints of which part should be replace first, location etc would be greatly appreciated.
