I live in flat, dry west TX. Picked up a 17 Sierra Denali Ultimate around the first of October. I listen to octane, turbo, boneyard. I have tried XM every day of my 3 month trial and the cutouts are almost constant, much more than it is actually in signal. My wife has had a 2010 Camaro SS for 7 years now and rarely ever has a cutout with her factory XM system and listens to the same exact stations. I have literally followed her while tuned to the same station to duplicate the conditions and her radio never misses a beat while mine struggles to get bits of a signal. I have sent refresh signals 4 times with no improvement. My 3 month trial ended today and I dropped the service. If they improve the antenna I will subscribe again but until then I will stick to bluetooth and fm.
