I have a Sirius lifetime account and I live in Canada if I go to the US will my Satellite Radio work?? Will I get XM channels??? How does the merger affect my account, since I live in Canada and XM and Sirius have not merged here??

PS: If anyone has dealt with Sirius in the past. Will it cost me monthly to have a second radio since I have a lifetime account?

PPS: Former Sirius owners how did the US merger affect your lifetime subscriptions??
