I had it a long ago, actually it first came out; I had two units of XM, in the house and in the car, plus online access; Sirius was on the opposite end; I enjoyed talk shows for the most part; the most recent XM we had it in our CRV when we bought it; eventually it all phase out and I never got it back; I couldn't justify the price, for a little time I use our CRV;
However, in this day and age, with all the smartphones out there there is no need for XM Radio IMO
