I'm wondering if this is a F-series problem or if i got a bum tuner. I'm thinking its the tuner. I've only had the XM connected for 2 days, and so far twice it has just gone silent. It started with what seemed like signal fade, with the station fading to a static-y type sound, and then it just goes completely silent. It never says that it lost signal, like it does when i pull into my garage, and the only way to fix it is to turn the car off and back on. Then it resumes playing like nothing happened.

 

Besides this i have to say the XM interface is really sweet on this thing. I've always had sirius, but went with XM because of how shitty the sirius interface is for the F, and I really like it. I even think it sounds better than Sirius, on most stations anyway.
