Well, I finally got an email from XM now as part of the merger with Sirius. I had already mentioned that I got an email from Sirius about their offer and I received a box from them 3 days later. Now I just have to find the time have it installed. 
XM Radio now allows you to do this by going to their website here if you have one of the following radios: Roady2®, SKYFi2®, MyFi®, Airware®, Tao, RoadyXT®, Xpress™, Sportscaster, XR9-XCX9, Jensen JXR9, inno®, Helix™, and Nexus®.
Their fix is to use Ferrite beads, a cassette adapter or an installation kit with hardware, which I am assuming is an FM transmitter. I guess I will see. I don’t see the Ferrite beads doing much except some passive induction filtering for stray high frequency noise unless the XM radios are also in violation of FCC Class B certification that the Sirius radios don’t have a problem with.
Here is the email I got from them:
Dear XM Subscriber,
The FCC has notified XM that some of our older receiver models (generally, those purchased before August, 2006) may not operate in the manner required by the FCC and may cause interference to nearby FM radio users depending on how the XM radio is installed or used.
The receiver models include the Roady2®, SKYFi2®, MyFi®, Airware®, Tao, RoadyXT®, Xpress™, Sportscaster, XR9-XCX9, Jensen JXR9, inno®, Helix™, and Nexus®. Please note this notice does not apply to you if your new car came installed with an XM receiver.
If you do have one or more of the receivers mentioned above and use it with the wireless FM option or you have had the receiver professionally installed, then we have several options available at no cost to you to alleviate this possible interference. Please visit our website at www.xmradio.com/fmmodinfo or call us toll-free at 866-410-0096 to choose one of the following three options:
Option A:
We will send you ferrite beads to attach to your XM antenna and power adaptor cables. (Ferrite beads are typically placed on the end of data cables to reduce interference.)
Option B:
We will send you a replacement cassette adapter to use with your XM radio. Only choose this option if your car radio has a cassette player.
Option C:
If your car does not have a cassette player, we will provide you with ferrite beads and an installation kit, with hardware, to use in connection with a professional installation of your radio along with a coupon redeemable at no charge for professional installation.
Please visit the following website, www.xmradio.com/fmmodinfo for more information and to select your option. If you do not have access to the Internet, you may call 866-410-0096 for information on how to alleviate this possible interference. To help expedite your order, please have your 8-digit Radio ID (found on Channel 0 of your XM radio) and your FCC ID (found on the back, the bottom, or under the battery of your XM radio), available when you start this process.
Thank you for your attention to this matter.
Best Regards,
XM Management
Note - If you are using your XM radio’s FM modulator to send the XM signal to a home or car stereo, your radio will work best if you use an unused FM frequency. Go to www.radio-locator.com/cgi-bin/vacant to find the best FM frequencies to use in your area.
