This vehicle was purchased new without any issues with the XM or radio system. Just this past February, started losing the XM signal. XM radio stations drop in and out where you cannot listen to XM at all. FM and AM part of the radio work fine. With much troubleshooting online and discussing with XM folks, problem was narrowed down to the XM receiver in the vehicle. GM Dealership replaced this unit, but it did not fix the signal loss. We are now at a loss of what to do. I have 5 other XM accounts, two of which are in Corpus Christi and all radios work fine without signal loss. I have even placed my portable XM in the car and it works fine. I guess sell the car and sell the problem. Any solutions to this would be appreciated. It is however, a very nice vehicle with no other issues to mention. What we have done: Contacted XM and no reports of issues like this in town Refreshed the signal several times Replaced the XM receiver in vehicle which provided a new radio ID number Removed any electronic devices in vehicle such as Cell phone, that could intefere

The only part not replaced would be the antenna. I hate to go back to GM without some type of proof that this could be the problem.
