About every 3rd time I get in my 2013 f350 the Sirius tries to update and just stays at 0% and the sync freezes. I have let it try to update for up to 30 minutes while driving and it never updates. if I shut the truck off and get out then get back in the sync is frozen and the only cure is to pull the fuse. Has been doing this since truck was new and dealer can not find a problem.
