I am still on the trial period on XM. Starting a few days ago, several of the channels I had on presets no longer work, and there are big gaps in the sequence of channels. Nothing on the XM website about this. Anyone else have this problem?

 

Give them (XM) a call and have them resend your signal - you'll need your XM ID - channel 1. That should fix it.

 

XM is running a promotion until June 7th for non-subscribers. Just started a week or so ago. Chances are, some of your channels got cut out during this promotion. But yeah I'd call them just in case.
