I don't understand the value of Sirius satellite radio, so it is clearly not for me. My Escape came with a 6 month sub for Sirius. I took one 6 hr (each way) trip when the subscription was active. We mostly listened to the "comedy" channel, and was surprised to hear (1) advertisements - I thought a fee-based radio would be ad-free, and (2) repetition - our trip was only 6 hours and we were hearing repeats after 4 hrs....
My $29,95 bluetooth earpiece works very well, and I can take it with me when I am walking around outside the car too.
