When the new vehicle trial was about to expire, I looked into the basic service. Web site does not let you sign up for anything, so I sent an email. They responded, telling me to call. Eventually, I Googled "Sirius Web Site Problems" and eventually landed on a Better Business Bureau list that has pages and pages of complaints. They overcharge, double bill, hang up on you if you try to cancel or downgrade, etc. A few years ago there was a class action suit along with action from several states Attorneys General. They paid off but continued with the same practices. After this research, I don't care how good or bad the service is, I will NOT do business with them. Fortunately, they don't have my credit card number. There were a few complaints that they got credit card numbers from new car dealers so they could automatically renew you.
