I got a used S50 from craigslist (I know what you're thinking, but it was from a police officer and I don't think he was tricking me or anything) and it can't get a signal at all. I'm thinking it might be something wrong with the cradle. It is impossible to listen to because it cuts out every second. I called Sirius and they told me to try a hard reset. I haven't done that because I figured I should come here first. If it is the cradle where can I get a new one?
