Be careful with those magnetic antennas they include, if they are put on the paint in a place you deem is out of the way and you don't ever move it to clean under it, they will cause that area under the magnet to rust and that can happen in a years time.
Sirius is expensive once your trial period ends, you can call them and say cancel it and they will offer you a good deal to keep it going but you will end up having to do that every year when it expires, they also have you on an automatic renewal so if you forget you all of the sudden get a larger amount charged to whatever card you gave them, now you have to get on the phone and threaten to cancel the service and again they will offer you a better deal, it is a never ending cycle with them.
I had two life time subscriptions but Sirus put restrictions on the life time subscriptions so you would lose the subscription after a certain number of transfers (5) for I think it was a $50 dollars transfer fee for the portable radios and in car radios they would not allow you to transfer to your new car. There is a lawsuit now over this and I was notified by mail, they are trying to get the court to force Sirus to honor the life time subscription and you would be able to transfer it without losing it for a fee of $75 dollars unlimited number of transfers you just have to pay the $75 dollar transfer fee each time you transfer it to a new car.
Sirus after they took over XM stopped offering the lifetime subscriptions.
