I called XM today to cancel my 3-month trial subscription since I was already a Sirius lifetime member and it turns out that my XM number had never been registered. Which means if I didn't call them, I would be getting XM free for life! If I didn't already get Sirius for life without a monthly payment, I might be pissed about this.
I still have to set up the car for Sirius now FTL!!
