My XM in '18 Tahoe Z71 will cut out quick if I'm going under a bridge or even just driving near tall trees even on the interstate. Anyone else have this problem? I've had Xm/Sirius in other vehicles. My last vehicle had a portable unit and I installed the little puck antenna for it and it almost never cut out, even going under bridges, unless it was a large one. I'm wondering can you add an aftermarket antenna for this system and make it better?
