this is a code for one year of xm for $77. For those of you who already have XM and are up for your annual renewal, call xm and tell them about the deal. If you don't, they will roll you over to a new rate with a quarterly bill. You may have to cancel your subscription to renew at the lower rate, I did and wound up losing 12 days of contract time (no big deal). I have used these codes for two years, and the coupon code changes from time to time. The rate is about 1/2 of the normal rate for what they call XM everything. If you call them at 877-291-5304 about your account you will probably not need the code.
