I have two Delphi XM Radio's. The one in my truck kept stopping and then saying check Antenna Connection. I have one in my house another Delphi Radio. It works. I paid for two radio's this last time I renewed. I think I will call them and see about them canceling my truck radio and then putting the balance on the other radio. I use it in my RV. My new truck I ordered comes with XM/Sirius Radio for one year.
