I just purchased a car that came with XM. Although I like it, I do not feel that it is worth the amount they are asking. 1. Anyone know if I purchase a home receiver with XM built in if I can use the same subscription used for my car also for the home receiver? Will I need to purchase a second subscription? 2. $12.95/month is more than I am willing to pay. What is a realistic amount to pay based on current promos/coupon codes out there? Thank you.
