If the audio system is tuned to a station that is not
broadcasting RDS information, the station's frequency
will remain on the display.
The RDS feature relies upon receiving specific
information from RDS stations. These features will only
work when RDS information is available.
TA (Traffic Announcement): 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. 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, use the
VOL up or down buttons during the announcement.
See "Voice Guidance Volume Settings" under Navigation
Set Up on page 2-41 for more information.
When a traffic announcement comes on the current radio
station, you will hear it even if the volume is muted or a
CD is playing. 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.

INFO (Information): When RDS is on, if the current
station has a message, INFO will appear on the display.
Touch INFO from the preset menu to view the message.
If the whole message does not appear on the display,
parts of the message will appear every three seconds
until the message is completed. Once the complete
message has been displayed, INFO will disappear from
the display until another new message is received.
INFO will remain available to allow you to display the
entire message again.
PTY (Program Type): PTY allows you to seek only
stations with types of programs you want to listen to.
This button is used to turn on and off Program
Type (PTY) features.
With RDS on, touch RDS, followed by PTY. The PTY
display will turn on. Touch RDS followed by this button
again to turn the PTY display off.
Select PTY (Select Program Type): With RDS and
PTY on, touch RDS, then Select PTY. The PTY
menu will appear. Use the up and down arrows to
select a PTY.
When the PTY display is on, press TUNE/SEEK or
SCAN to find radio stations of the PTY selected. The last
PTY selected will be used for seek and scan modes.
If a station with the selected PTY is not found, STATION
NOT FOUND will appear on the display. If both PTY
and TA are on, the audio system will search for stations
with traffic announcements and the selected PTY.
