Beware of Sirius Radio!! They have a fradulant method of theft. When you sign up and give sirius your credit card, you are automatically set up for automatic renewal!! If you sign up for anything longer than 1 year program, you are billed for a renewal without your consent. Most of the time, your credit card will have already expired. Then you are sent to collections. The collection company then tells you to call sirius radio to "correct" the error. Sirius Radio then tells you to call the collection company. Sirius will tell you that they are supposed to inform you of this when you sign up but as I have had sirius in 3 different vehicles, I know this is a LIE!!!
