XM radio service renewal

I just renewed the XM radio service on my 06 XLR for a year @ $77.00. Heres how you can also get in on this special. Simply call 1-800-892-5400 and when the operator answers, tell her you want to renew your subscription under the special promotion "ZWINBACK". Some people have had to call a couple times to get it done, but I did it today in one try. You'll need your account number for XM, which we all have from when we bought the cars. They were very helpful and I think this offer is for a very short time, so call right away if you're interested. I found this info on the corvette forum of which I'm also a member. Good luck. Bill
