Table 1: RDS Program Type (PTY) Selections

The audio system has been designed to operate easily and give years of listening pleasure. You will get the most enjoyment out of it if you acquaint yourself with it first. Find out what your audio system can do and how to operate all its features, to be sure you're getting the most out of the advanced engineering that went into it.

The ignition must be in a position other than OFF or retained accessory power must be active for your audio system to work. See "Retained Accessory Power (RAP)" in the Features and Controls section of your owner's manual for more information.

Adjusting the Speakers


Object Number: 952375  Size: B3

SPACIOUS: This button is used to make the listening space seem larger.

SOUND: Touch this button to access the Sound menu. See "Sound Menu (Tone, DSP, Fade and Balance)" listed previously in this section for more information.

Radio Data Systems (RDS)


Object Number: 1200969  Size: B3

Your audio system is equipped with Radio Data Systems (RDS). RDS mode gives you many useful new features. When RDS is on, the audio system can:

    • Seek to stations with traffic announcements,
    • receive announcements concerning local and national emergencies,
    • receive and display messages from radio stations and
    • search for a stronger station when a station is too weak for listening.

RDS features are only available for use on FM stations which broadcast RDS information.

RDS:  Touch this button to use the alternate RDS functions located in the preset menu for FM 1/2 only. When you touch RDS, you will only have approximately five seconds to choose RDS ON/OFF, TA, MSG, PTY or Select 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 approximately five seconds, if available, the program type will be replaced on the display by the station's program type name. The program type and program type 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, when a station gets too weak for listening.

The RDS feature relies upon receiving specific information from the RDS stations. These features will only work when RDS information is available.

TA: Touch this button to receive traffic announcements. The audio system will turn on the TA display. TA will appear on the display if the tuned station broadcasts traffic announcements. You may also receive traffic announcements from stations in the network related to the tuned station. If the current tuned 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, the TA icon will turn off. While a traffic announcement plays, the audio system uses a special type of volume called 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 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 compact disc 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 compact disc player was being used, the compact disc will stay in the player and resume play at the point where it stopped. Touch the RDS button, followed by the TA button again to turn TA off.

MSG (Message): When RDS is on, if the current station has a message, the MSG icon will appear on the display. Touch the message button from the preset screen 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, the MSG icon will disappear from the display until another new message is received. The message button will remain available to allow you to display the entire message again.


Object Number: 1200969  Size: B3
PTY: 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 the RDS button, followed by the PTY button. The PTY display will turn on and will appear on the display. Touch the RDS button, followed by this button again to turn the PTY display off.

Select PTY (Select Program Type):  With RDS and PTY on, touch the RDS button, then the Select PTY button. The PTY menu screen will appear. Use the scroll up and down arrows to select a PTY. Touch your PTY selection and the system will return you to the screen with the preset stations shown. See Steps 1 through 7 under "Preset Station Menu" to store the selected PTYs. The selected PTY is then stored on the preset. You can now touch the PTY preset to recall your settings. When the PTY display is on, press TUNE/SEEK and 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, NONE 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.

PTY (Program Type) Presets: The six preset buttons let you return to your favorite Program Types (PTYs). These buttons have factory PTY preset stations. See "RDS Program Type (PTY) Selections" later in this section. You can set up to 12 PTYs (6 FM 1 and 6 FM2). To save a PTY preset, do the following:

  1. Touch the FM 1/2 source button.
  2. Touch the RDS button to enter the RDS menu.
  3. Touch the RDS ON/OFF button to turn RDS on.
  4. Touch the PTY button.
  5. Touch the Select PTY button and select the desired PTY from the list. See "RDS Program Type (PTY) Selections" following for a listing of PTYs available.
  6. Touch and hold one of the six buttons for more than two seconds or until you hear a beep. Whenever you touch that numbered button for less than two seconds, the PTY you set will return.
  7. Repeat the steps for each preset button.

Once you have stored a PTY for each of your preset stations, you can recall a PTY preset by touching the preset station for less than two seconds. Then use TUNE/SEEK or SCAN to locate a station for that PTY selection.

When battery power is removed and later re-applied, you will not have to reset your RDS preset stations because the audio system remembers them.

ALERT: This type of announcement warns of national or local emergencies. You will not be able to turn off alert announcements. Alert announcements will come on even if RDS mode is turned off. ALERT appears on the display when an alert announcement plays. The audio system uses TA volume during these announcements. To increase volume, touch the VOL button on your steering wheel or use the VOL up and down buttons during the announcement. See "Voice Guidance Volume Settings" under Setup Menu for more information. When an alert announcement comes on the tuned radio station or a related network station, you will hear it, even if the volume is muted or a compact disc is playing. If the audio system tunes to a related network station for an alert announcement, it will return to the original station when the announcement is finished. If the compact disc player is playing, the player will stop for the announcement and resume when the announcement is finished.
