Update...Moving the antennae apart fixed all the XM issues. Now the only issue is with the GPS. At times, the GPS thinks I'm off-roading & it when I slow down to stop, the map keeps moving forward & then it thinks I'm in the middle of a field. When I turn onto a different road, it realizes I've turned & then it puts me in the correct spot. This isn't typically a problem, but if my wife is driving downtown & there are lots of streets, it's an issue. Any help is appreciated! This has become one giant hassle.
