We have a 2007 Mustang with a Shaker 500 audio system. Just recently the Sirius radio will only go from Channels 98-140. I called Sirius and they sent several signals to the radio but to no avail. I recently ordered a SC-C1 Sirius Module (this is on recommendation from several websites) and was wondering if anyone has had this problem and if they used the same item? Do I just need to replace the Sirius Module that is in the trunk with this new one? Any help would be appreciated.

Thanks

 

just replace it. Probably went bad due to some defect on board.
