Thread: -Need Help!- 2006 Grand Prix Monsoon 6 CD in dash changer W/O XM iPod Interface.

you need to search for the unlock code procedure there is a way to get around the dealer, but it your calling a GM tech number, giving a dealer code, they are on line, then pushing the # that show up on the locked radio. it will tell you what code to enter into the radio. its automated, so your not talking to any one.

XM works on the ID # thats in the radio. so signing up is as easy as a phone call.

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.
