XM reception problem
More than a problem, it seldom works at all. Took del of my car a couple of weeks ago. Drove off the lot and the XM reception became intermittent. Like a loose antenna lead. Took it to the dealer the next day for a look see. They said it couldn't be an antenna and that I must leave it for a day. Dropped it off a couple of days later and was then told I needed a new radio. Took 48 hours to get a new one. Still did the same thing. Now the dealer tells me it needs a new antenna but Chevy doesn't have any in stock anywhere. It must come direct from the supplier and will take close to a week.
I have seen all sorts of posts about XM issues but not nothing close to this problem. Any thoughts or advice?

Did they actually check all the fittings to the antenna? If this is your second radio and the problem is exactly the same as described ,,,, other than a faulty attenta itself, what the heck else could it be but a loose fitting (s)??

My XM Radio cuts in and out on the right channel depending on the day of the week. AM/FM and CD are not affected.
This is going to sound dumb, but if the right channel cuts out I press on the top of the Nav panal and the sound pops back in.
I've only had the car two weeks so I'm going to live it for awhile before I bring it in.

Update: The dealer says that it will take at least 2 weeks to get the new antenna in. Of course, they are only guessing as it is the final part to replace. The time to get it is just a guess also as there is none to be found through conventional channels. I think of antennas as being a cable and a receiving peice. Are they more complicated and technical nowadays? It just doesn't seem this complicated.

This should answer some of your questions
I may have posted this before, but likely not in this thread? The following comes from a very high source and you can trust what's being said. I received this on March 31, 2005
--------------------
This is a condition that Denso (Radio
manufacture) is aware of. It has to do with the sequence the radio uses to
power up the radio. There are times when the radio gets powered up before
the antenna sees the antenna module so the static is there because the radio
can't locate the antenna. Switching the radio to AM and back to FM allows
the radio to attach to the signal and the static should be gone. Denso is
working on a file-fix that will allow dealers to reprogram the radio in
the dealerships. the repair should take about 10 minutes when it is
completed. I don't have an accurate timing on the fix but it should be in
120 days or less.

I would be interested in knowing if you've talked with your dealer regarding the Denso file-fix, if it's now available, or when they think it might be available? Thank you as well, for your update.

Keep hearing about a software fix that "silvercoupe" had done at his dealer.
Talked to a guy down the block from me and his is perfect so it is an equipment and not xm service problem i would suppose.
Keep us informed - looking forward to hearing from you after the new antenna install.

The dealer got in the new XM wart yesterday and installed it. My XM now works great. For those that have fading or hissing when not under a roof or overhead structure, you may need to have your antenna changed. They are not a common stock item and takes a while to get one.

My car is at the dealer right now for the same exact issue-intermittant signal reception. 
The radio had never seemed to work, but I couldn't part with the car long enough to have it checked out if you know what I mean.
The issue according to early reports is not the antenna, but a module that is near the tail lights.
Hope this fix works and also hope that GM will extend my trial period for the XM. So far even ignoring the static and fadeouts, I'm not sold on this whole program.
