Acura 2008 RL - Manual (Page 227)

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.
Because XM is unavailable in Alaska,
the XM hardware equipped with
your vehicle cannot be operated.
