RDS: Touch RDS to use alternate RDS functions located
in the preset menu. When you touch RDS, you will only
have about five seconds to choose RDS ON/OFF, TA,
MSG, PTY, or SEL PTY. If you do not make a selection,
the system will return to the previous menu.
If you are tuned to a station broadcasting RDS
information, the station's Program Service (PS) and
Program Type (PTY) will replace the station's frequency
on the status line at the top of the display. After about
five seconds, if available, the PTY will be replaced
on the display by the station's PTY name. The PTY and
PTY name may be the same or different.
If the audio system is tuned to a station that is not
broadcasting RDS information, the station's frequency
will remain on the display. While RDS is on, the
audio system will search for a stronger station in the
network if a station gets too weak for listening.
The RDS feature relies upon receiving specific
information from RDS stations. These features will only
work when RDS information is available.
TA (Traffic): Touch TA to receive traffic
announcements. The audio system will turn on the TA
display. TA will appear on the display if the current station
broadcasts traffic announcements. You may also receive
traffic announcements from stations in the network
related to the current station. If the current station does
not broadcast traffic announcements, the audio system
will seek to a station which will. When the audio system
finds a station which broadcasts traffic announcements, it
will stop. If no station is found, TA will turn off.
While a traffic announcement plays, the audio system
uses TA volume. To increase TA volume, touch the VOL
button on your steering wheel or use the VOL up or down
buttons during the announcement. See "Voice Guidance
Volume Settings" under Setup Menu on page 4-7 for
more information.
When a traffic announcement comes on the current radio
station or a related network station, you will hear it even if
the volume is muted or a CD is playing. If the audio
system tunes to a related network station for a traffic
announcement, it will return to the original station when
the announcement is finished. If the CD player was being
used, the CD will stay in the player and resume play at
the point where it stopped.
Touch RDS followed by TA again to turn TA off.
