oem xm radio

I have a 2003 2500hd with cd and want to upgrade to a factory xm radio/6 disc changer. Not having any luck locating parts. Any ideas other than the dealership would be greatly appeciated.

try e-bay. they have tons of stuff ususally

i would say ebay also, but be careful because some of the newer style radios will only work in the original vehicle that they are in, becuase they pick up a memory code from the bcm to keep the vin number and will only lock up when in any other vehicle unless gm reprograms it. and they will rip you off to do so.
