SiriusXM offers pre-owned vehicle owners a SiriusXM Internet Radio 60-Day Trial for free when you fill out a short form. (You'll be asked for your vehicle's VIN number). That's the longest free trial deal we've seen from SiriusXM this year. (For further comparison, we saw a 30 day trial last month.) This trial includes access to every SiriusXM channel (including Howard Stern) and can be listened to on a computer, iPhone, iPad, iPod touch, or many Android devices. No credit card information is required.
