I got my xm antenna on top of my strut bar in the rear window, it has worked fine from day one with a full signal. Now I got my windows tinted today the legal limit for here(not sure what that is) and the xm fades in and out like crazy.. This happen to anyone else? I wonder if the dude hit the antenna while he was tinting the trunk, or is the tint blocking the signal? my only other option is to move the antenna to the front wind shield and sit it on the dash but is a pain in the butt and i don't want it their.. What do you guys think?
