Hey everyone, I got my 2011 Terrain in September and I've been having problems with serious static through the speakers whenever an iPod or iPhone is hooked up playing music. If I switch to stereo, it's fine, but the minute I go back to iPod, the static continues. It lasts for about 20 minutes and there's no telling when it will start.. I've brought it in so many times and they've replaced parts, but it still does it. And GM refuses to put in a new stereo unit. Is anyone having these problems?? Thanks!!
