Hey guys, i just took delivery of my 2010 gmc sierra work truck. I cant stand the am/fm radio and i would like to find a stock radio with xm/cd player. I have found a website that sells OEM delco radios for 400 bucks. But i know the thing is theft locked and has to be programmed by the dealer. Does anyone know exactly howmuch this cost and does anyone have a stock radio sitting around they would be willing to sell? I dont have onstar and i really dont care for aftermarket radios. also does anyone know if my truck is prewired for xm? i found replacement fish tail antennas. Thanks Guys!
