I'm wondering if anyone else has "lost" their antenna... I noticed someone had one on their car and then went to research if the '11 equinox's did indeed come with an antenna. Seems as if I have lost mine somehow. It looks as if the antenna just screwed out of where it was. I don't listen to AM/FM really so I never noticed any reception loss. Not sure if this is the same antenna for XM. Anyone wondering how much this would be to replace? Or if I should even bother to replace it? I know for a fact I had an antenna at one point in time because I have a picture from one of the first days I got my nox. ???
