Since your Cherokee already has XM available, everything should work other than what NScherry said to do. Look at the first couple pages of this thread and see what all I did. I saved a lot of money by getting the activation code online rather than going to the dealer. Also if your Cherokee doesn't come with heated seats or steering wheel already, I'm pretty sure you can't add them unless you physically buy a new wheel or leather seats or something.
