XM - no signal
Just bought a 2005 c6 with the factory Nav/XM/Bose head unit. Activated XM online today, and now I see that I'm getting no XM signal. Any suggestions on how to troubleshoot this?
The XM screen just continually reads "No Signal."

Any chance you're in a garage or under heavy trees? If yes, drive out to an open road and see if you get reception.
If nothing, check the antenna connections on the XM box. It's located under the plastic overhang that's right above the drivers side rear wheel hump. Just pull the carpet out/down and you'll see the box. There are 2 plugs for the antennas, IIRC yellow and green, both about 1/4" in size.

Can you change stations? I think you may have to leave the radio on channel one for the receiver to get data from the satellites. Set the car to channel one the next time you are driving around.
Have you called XM regarding this problem? Its possible that XM has to re-send the activation signal.

Called XM. They were very helpful but to no avail. I got excited for a brief second when they "reset" my radio - there was a message on the screen that read "loading XM" followed by about 2 seconds of audio on the preview channel, then static, then back to "no signal." Dang. She told me the next step would be to take the car to a professional tech and have the module checked. Grrrrrrr!!!!!!

While this is a known issue; I believe at this point in time they're dealing with it on a case by case basis. With that being said, I'd recommend taking it to the dealership.

I have a 2009 GMC Sierra truck with OEM XM Radio that has worked perfectly for two years and now it says No XM Signal as well. Of course I called XM and they did their usual 'reset' thing. No fix. I seriously doubt this is a GM/Radio problem. However, since there are no English-speaking Americans at XM tech support they just go by their script and pass the blame onto someone else.
I have noticed many recent reports of XM service outages in the past couple of months. Anyone get any real answers regarding this issue?
