XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio reception from coast-to-coast in the 48 contiguous United States, and in Canada. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy foliage, bridges, garages, or tunnels can cause loss of the XM™ signal for a period of time.
The radio could display NO XM SIGNAL to indicate interference.
