RDS
Overview of the RDS
function
Radio Data System (RDS) is a broadcasting
service that allows FM stations to send
additional digital information along with the
regular radio programme signal. Your car
stereo offers you a variety of services. Here are
just a few: retuning the same programme
automatically, listening to traffic
announcements, and locating a station by
programme type.
Notes
• Depending on the country or region, not all of
the RDS functions are available.
• RDS may not work properly if the signal strength
is weak or if the station you are tuned to is not
transmitting RDS data.
Displaying the station
name
The name of the current station lights up in the
display.
Select an FM station (page 11).
When you tune in an FM station that
transmits RDS data, the station name
appears in the display.
Note
The “*” indication means that an RDS station is
being received.

13
Retuning the same
programme automatically
— Alternative Frequencies (AF)
The Alternative Frequencies (AF) function
automatically selects and retunes the station
with the strongest signal in a network. By
using this function, you can continuously
listen to the same programme during a long-
distance drive without having to retune the
station manually.
1Select an FM station (page 11).
2Press (AF) repeatedly until “AF-ON”
appears.
The unit starts searching for an alternative
station with a stronger signal in the same
network.
Notes
• When there is no alternative station in the area
and you do not need to search for an alternative
station, turn the AF function off by pressing
(AF) repeatedly until “AF-OFF” appears.
• When “NO AF” and the station name flash
alternately, it means that the unit cannot find an
alternative station in the network.
• If the station name starts flashing after selecting
a station with the AF function on, this indicates
that no alternative frequency is available. Press
either side of (SEEK/AMS) while the station name
is flashing (within eight seconds). The unit starts
searching for another frequency with the same PI
(Programme Identification) data (“PI SEEK”
appears and no sound is heard). If the unit
cannot find another frequency, “NO PI” appears,
and the unit returns to the previously selected
frequency.

After you select the desired item, the display
will automatically change to the Motion
Display mode after a few seconds.
In the Motion Display mode, all the items are
scrolled in the display one by one in order.
Tip
The Motion Display mode can be turned off. (See
“Changing the sound and display settings” on
page 20.)
Note
“NO NAME” appears if the received station does
not transmit RDS data.

14
Listening to a regional programme
The “REG-ON” (regional on) function lets you
stay tuned to a regional programme without
being switched to another regional station.
(Note that you must turn the AF function on.)
The unit is factory preset to “REG-ON,” but if
you want to turn off the function, do the
following.
1During radio reception, press (MENU),
then press either side of (PRST)
repeatedly until “REG” appears.
2Press the (+) side of (SEEK/AMS) until
“REG-OFF” appears.
3Press (ENTER).
Note that selecting “REG-OFF” might cause
the unit to switch to another regional
station within the same network.
To return to regional on, select “REG-ON” in
step 2.
Note
This function does not work in the United
Kingdom and in some other areas.
Local link function
(United Kingdom only)
The Local Link function lets you select other
local stations in the area, even if they are not
stored on your number buttons.
1Press a number button that has a local
station stored on it.
2Within five seconds, press the number
button of the local station again.
3Repeat this procedure until the desired
local station is received.
Listening to traffic
announcements
The Traffic Announcement (TA) and Traffic
Programme (TP) data lets you automatically
tune in an FM station that is broadcasting
traffic announcements even if you are listening
to other programme sources.
Press (TA) repeatedly until “TA-ON”
appears.
The unit starts searching for traffic
information stations. “TP” appears in the
display when the unit finds a station
broadcasting traffic announcements.
When the traffic announcement starts,
“TA” flashes. The flashing stops when the
traffic announcement is over.
Tip
If the traffic announcement starts while you are
listening to another programme source, the unit
automatically switches to the announcement and
goes back to the original source when the
announcement is over.
Notes
• “NO TP” flashes for five seconds if the received
station does not broadcast traffic
announcements. Then, the unit starts searching
for a station that broadcasts it.
• When “EON” appears with “TP” in the display,
the current station makes use of broadcast traffic
announcement of other stations in the same
network.

15
To cancel the current traffic
announcement
Press (TA), (SOURCE) or (MODE).
To cancel all traffic announcements, turn off
the function by pressing (TA) until “TA-
OFF” appears.
Presetting the volume of traffic
announcements
You can preset the volume level of the traffic
announcements beforehand so you won’t miss
the announcement. When a traffic
announcement starts, the volume will be
automatically adjusted to the preset level.
1Turn the volume control dial to adjust
the desired volume level.
2Press (TA) for two seconds.
“TA” appears and the setting is stored.
Receiving emergency
announcements
If an emergency announcement comes in while
you are listening to the radio, the programme
will be automatically switched to it. If you are
listening to a source other than the radio, the
emergency announcements will be heard if
you set AF or TA to ON. The unit will then
automatically switch to these announcements
no matter which source you are listening to at
the time.
Presetting the RDS
stations with the AF and
TA data
When you preset RDS stations, the unit stores
each station’s data as well as its frequency, so
you don’t have to turn on the AF or TA
function every time you tune in the preset
station. You can select a different setting (AF,
TA, or both) for individual preset stations, or
the same setting for all preset stations.
Presetting the same setting for all
preset stations
1Select an FM band (page 10).
2Press (AF) and/or (TA) to select “AF-ON”
and/or “TA-ON.”
