I just tried XM radio and it's pretty nice. But when I drove off the dealer lot, they didn't tell me that I get the service free for first 3 months.

So wut happens after my free subsciption expires? will i get charged after the 3rd month without warning or will the service stop and need to renew?

 

The serivce would stop and you would have to renew. XM sends you a letter telling you when the service is going to disconnect and tells you how to subscribe. I personally didn't renew but at least if i would like XM radio down the road I don't need to buy any additional equipment.

 

Yes, they will send you numerous "renew today" notices by mail. There is no way they could charge you since they do not have any of your payment information.
