stations.
This system relies on receiving
specific information from these
stations and only works when the
information is available. It is possible
that a radio station could broadcast
incorrect information that causes the
radio features to work improperly.
If this happens, contact the radio
station.
When information is broadcast from a
RDS station, the station name or call
letters display on the audio screen.
Radio text supporting the currently
playing broadcast may also appear.

programming and commercial-free
music, coast to coast, in digital-quality
sound. In the U.S., see
www.siriusxm.com or call 1-888-601-6296. In Canada, see
www.siriusxm.ca or call

Radio Reception
Unplug electronic devices from the
accessory power outlets if there is
interference or static in the radio.
FM
FM signals only reach about 16 to
65 km (10 to 40 mi). Although the
radio has a built-in electronic circuit
that automatically works to reduce
interference, some static can occur,
especially around tall buildings or
hills, causing the sound to fade in
and out.
AM
The range for most AM stations is
greater than for FM, especially at
night. The longer range can cause
station frequencies to interfere with
each other. Static can also occur when
things like storms and power lines
interfere with radio reception. When
this happens, try reducing the treble
on the radio.
