Has anyone experienced this problem ? On our trip to Kerrville and back the Satellite Radio Receiver would intermittently display "no signal" and "antenna." With this display we were unable to receive any stations. Now that we are back in our home territory of Florida and North Carolina it is working fine. The XM Antenna is secure on the roof and there are no connection problems between the receiver and the aux side of the Bose Stereo system. Did anyone else experience poor reception on their trip ? Is additional programming required for different areas of the country ? I tried contacting the XM help desk but the middle eastern and I could not understand each other and I gave up.
