Yes you can add xm to the factory radio as long as it has the band button. You need 3 things. An XM antenna i recomend the TERK Micro its the smallest xm antenna out there. Also the Pioneer GEXP910XM, and a Soundgate PIOGM1V4 the soundgate product integrates into the factory deck simply plugs in and uses the stock deck to control and display the pioneer unit. I install these all day long its the best working system to add to a STOCK head unit in any of the chevys. Otherwise a cheaper route would be to simply add a TERK XM commander and if you got the center console you flush mount the unit into the top pocket. I have pictures of one if youd like to check it out.
