if your stock radio dont have XM, it dont have XM, end of story. find a better stock radio with XM. or external cd player, then you can tap into that.


the unlocking is if you get a new radio (a stock one from another car) it will lock when you plug it in. then you'll need to unlock it. its a theft deal.
