Bought my daughter a new XM receiver for her birthday a couple of weeks ago, signed her up for a year, and everything worked fine for 2 weeks. Now it appears the receiver is constantly loading and reloading and nothing is coming in. I think it could be a reception problem and maybe the repeaters aren't working in D.C. , but XM is still trying to tell her it a bad unit. I would appreciate any thoughts or suggestions about this problem. Thanks for all.
