I have the factory installed Sirius package and sometimes when I start my truck the reception is very fuzzy. This has happened a few times and will not go away unless I shut off the truck and restart it. All other radio/cd functions work just fine when this is happening. I took a 2 hour drive over the weekend and it happened to me then. After about 45 minutes I pulled over and shut the truck off, restarted and everyting was fine. I'm stopping by the dealer Friday, but was curious if anyone had any ideas as to why this is happening?
