I just signed up with XM and the best of Sirius. I was 16.99 a month with taxes it was $218 for a year, ouch! Online computer hook up is free but you don't get the whole package.
I have been destroying computer burned CD's for years I wanted to try XM and the best of Sirius...you can change the prepaid services to your new Camaro. It sounds great!!
You get a discount for signing 2 or 3 years.
XM is $12.99 a month.
