My Sirius radio reception and volume is very weak on my 2007 Navi. I can't hear it at all unless I turn the volume up all the way to maximum and am sitting still at a stop light because of background noise, even then I can barley hear it. My AM/FM and CD player all work perfect. Has anyone else had this issue?

 

I disconnected the battery for about 30 seconds, now Sirius Radio reception is back loud and clear again.
