I got XM with my new car purchase for 6 months and am enjoying it and was considering keeping it even though the car is only used on the weekends.

After reading this thread about the difficulty to cancel, I doubt we will keep it.

FWIW - I just received and email from them clearly stating that by signing up, you are also signing up for auto-renew and unless you call to cancel, will be responsible for the charge.

I also think OnStar is exactly the same. They duped me into giving me my credit card number to pay for 60 minutes of telephone time, and then signed me up for auto-renew. I went to the website to check something else out and saw that not only was I on autorenew, but it could only be cancelled if I called. That call took 15 minutes - just to get rid of auto-renew.

These companies are shooting themselves in the foot. I'm not going to renew either because of these tactics. I was going to renew both.
