The XM satellites are in orbit over the equator; therefore, objects south of the vehicle may cause satellite reception interruptions. To help compensate for this, ground-based repeaters are placed in major metropolitan areas.
Satellite signals are more likely to be blocked by tall buildings and mountains the farther north you travel from the equator. Carrying large items on a roof rack can also block the signal.
Depending on where you drive, you may experience reception problems.
Interference can be caused by any of these conditions:
Driving on the north side of a large commercial truck on an east/west road.
Driving in tunnels.
Driving on a road beside a vertical wall, steep cliff, or hill to the south of you.
Driving on the lower level of a multi-tiered road.
Driving on a single lane road alongside dense trees taller than 50 ft. (15 m) to the south of you.
Driving on the north side of an east/west mountain road.
Large items carried on a roof rack.
There may be other geographic situations that could affect XM Radio reception.
