garfull 
took my head unit out and i disconnected the cable that going from my XM to my radio and i shouldnt be hearing any noises but i still hear same noise no matter if anything connected to my radio or not so it cant be the XM. I even tryed this http://www.crutchfield.com/App/Produ...5&c=11&tp=2653
Didnt help and then i went deeper and in my wire hardness i have ground and the antenna that going in my radio has ground also. I cut the ground cable in my hardness and leave just antenna in my radio was still working so antenna gives me the ground then i tryed connebt ground wire in my hardnes back on and disconnect the antenna,radio work and engine noise is still there also. When engine is off everything works fine but as soon as i start VX noise cames back on. I have no clue now what it can be =(
