I don't need to unlock the radio. I want to know if reprogramming the head unit is necessary to activate the XM circuitry in a head unit that never had a factory XM receiver originally installed.

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.
