I just picked up my used 2014 FFE yesterday. When I switched to satellite radio, all the channels worked, but there was a box stating no signal in the middle of the display while the bottom left corner read acquiring. I was able to fix the problem by doing a radio refresh: https://care.siriusxm.com/retailrefresh_view.action
