Hello,

I just got my 2013 Chevy Captiva Sport LTZ. Nice ride. In my old wheels, 2010 Ford Escape, the only time I "lost" satellite reception was under a bridge, parking garage or 'really' obscured overhead objects. Now on this new vehicle, the factory installed XM signal drops out frequently on tree lined roads. (The same ones I have been travelling for years without loss). Is there an adjustment or optional antenna to solve this one? The regular radio is fine. Thanks
