The Entertainment System on this vehicle is configured with either a base or an uplevel system. Both the base and uplevel systems contain a radio, antenna, and speakers.

The uplevel system differs from the base level system by providing the customer with enhanced audio system features. Some of those features include the radio data system (RDS), BOSE speakers, a radio interface module (RIM), digital signal processing, weather capabilities and a remote playback device.

The following list shows the radios available for this vehicle:

Each item in the list below represents topics covered in detail below.

Radio Signal

The radio signal is sent from a broadcast station and is then received by an antenna. The strength of the signal received depends on the following:

AM Reception

The AM band has a lower frequency range than the FM band. These longer wavelengths:

The AM frequencies have longer range due to the ground wave. The ground wave follows the curvature of the earth and is effected by its conductivity. Greater conductivity equates to less signal loss thus transmission over water is better than over land. The AM band has a range of 80-320 km (50-200 mi).

FM Reception

The shorter wavelengths of the higher frequency FM band:

Broadcasts in the FM band are limited to "line of sight" reception which is typically 40km (25 mi). Even when out of a direct line of sight, the signal may be reflected into areas that would be in a "shadow" otherwise. Factors which affect the line of sight include:

The "Theftlock" theft deterrent system is a feature on all base and uplevel radios. There is no need to program a security code into the radio as in past model years. The theft deterrent system now utilizes class 2 serial data to determine if the radio is in the appropriate vehicle. Each time the radio receives the "run" power mode message, it compares the VIN information it has stored to the VIN information received from the class 2 serial data circuit. If a mis-match occurs, the radio display will indicate to the user the radio is locked. Once this takes place, a DTC will set, the radio will not respond to any button presses and become inoperative. The 2 scenarios able to cause this condition are:

The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.

The remote CD changer allows for multiple compact discs to be played continuously without having to manually change compact discs. Normal size discs may be played using the slots supplied in the magazine. The magazine must first be loaded with discs before it can played. To load CD's, insert the CD's from bottom to top, placing the discs in the magazine label side down. If a disc is loaded label side up, the disc will not play and an error will occur. Care should be used to align and insert the disc into one disc tray only. Repeat this procedure for loading all of the discs in the magazine. Once the discs are loaded into the magazine, push the magazine into the changer in the direction of the arrow marked on the magazine and close the door. When the CD magazine is loaded, the changer will begin checking for discs in the magazine. This will continue for up to one and a half minutes, depending on the number of discs loaded. To eject the magazine from the player, push the CD changer door. The magazine will automatically eject. Whenever a CD magazine with discs is loaded in the changer, the CD changer symbol will appear on the radio display. If the CD changer is checking the magazine for CD's, the CD symbol will flash on the display until the changer is ready to play.

If one of the following codes appears in the radio display when the radio is first turned on, it is equipped with the home and away feature.

This feature allows 2 different drivers to store and recall specific radio settings. The settings recalled by the radio are determined by which remote keyless entry (RKE) transmitter (1 or 2) is used to enter the vehicle. The number on the back of the RKE transmitter corresponds to driver 1 or driver 2. The radio settings automatically adjust to where they were last set by the identified driver. The settings can also be recalled by briefly pressing the MEMORY seat button 1 or button 2 located on the driver's door.

The radio can store home and away presets. Home and away presets allow you to use 1 set of preset radio settings in the area where you live, and another set when you go out of town. That way, you do not need to reprogram your presets every time you travel. With the radio off and the clock displayed, use FF and RW to select home or away presets. In order to select the away presets, press and hold FF for 5 counts until you hear a beep. The next time the radio comes on, the away presets are active. In order to select the home presets, press and hold RW for 5 counts until you hear a beep. The next time the radio comes on, the home presets are active.

When battery power is removed and later applied, you do not have to reset your home radio presets because the radio remembers the presets. However, you do have to reset the away radio presets.

All uplevel audio systems are equipped with technology known as the Radio Data System (RDS). RDS is a system that sends data along with the audio of the FM station you are currently tuned to. RDS is a standard that defines how a FM broadcast station may send digital data along with the audio program. Think of it as a one way wireless modem, allowing the broadcaster to send information about his program to your receiver.

RDS data is carried in what is known as a "subcarrier". A subcarrier is a frequency that the FM broadcaster is authorized to use to send data or other audio programs that are not audible in the main audio program. RDS information can be used to display program information and to control the radio.

To receive the RDS signal, all that is needed is an FM receiver with a RDS circuit. A special integrated circuit capable of dealing with the RDS signal is in the RDS circuit and passes it along to the receiver's microprocessor where it is decoded and acted upon.

RDS Basic Information

RDS basic information:

In some cases, a radio station broadcasting incorrect information may cause the RDS features of the radio to appear to work improperly.

Broadcast RDS information can be used in a variety of ways by the receiver and listener, but basically falls into two categories: Display and Control.

Displaying Program Information

RDS displays textual information such as:

Turning RDS on

The RDS select button is located in the lower right hand corner of the radio face. Press the RDS select button to use the alternate RDS functions on the six preset buttons. After pressing the RDS select button, press the RDS (preset 1) button to turn RDS on or off. When tuned to a non-RDS station, your radio will display frequency information as you would normally expect. When tuned to an RDS station, your radio will change from displaying the frequency of the FM station to displaying the call letters of the station or display the nickname of the station. This feature is known as the Program Service Name.

Using the RDS Traffic Feature

Some RDS broadcasters may carry traffic information programming to inform you of current traffic conditions in your listening area and is indicated by the TP icon in the radio display. RDS enables the broadcaster to get this information to you even when you are listening to a tape or compact disc. This feature can be enabled or disabled by the listener. Press the RDS select button, followed by the TA-preset 2 button to find a station that claims to carry traffic information. You may do this even when playing a cassette tape or compact disc. This action will operate in the background without interrupting the current playback. If the radio is not currently tuned to an RDS traffic station, the radio will immediately SEEK an RDS traffic station. If the radio finds an RDS traffic station, the TP icon will appear in the radio display. If the radio cannot find an RDS traffic station after searching through the entire FM band, the radio will display "NONE FOUND".

Viewing Messages

When MSG appears on the radio display, a new message is available for viewing. These messages are from the RDS broadcaster and may be general information such as artist and song title. To view the text message, press the RDS select button, followed by the MSG-preset 3 button. If the whole message does not appear on the display, parts of the message will appear every 3 seconds until the message is completed. To view the message faster, press the MSG button again.

Using Program Type Presets

The radio has the ability to use RDS data to find stations according to program type (PTY). When in PTY mode the preset buttons are now PTY presets instead of frequency presets. To turn PTY mode on or off, press the RDS SELECT button, followed by the PTY-Preset 4 button.

Selecting a PTY

The preset 5 & 6 buttons can be used to scroll through the list of available program types (PTY) that can be used to find RDS broadcasts. Press the RDS SELECT button, followed by the preset 5 or 6 button to scroll through the available program types. The radio will show the PTY icon to indicate that it is in PTY mode. When the desired PTY is shown on the display, press the TUNE/SEEK button. The radio will search for an RDS broadcaster that is carrying the PTY you selected. If the TA icon is displayed while performing a PTY search, the radio will look for an RDS broadcaster of both the selected PTY and traffic information. If the radio cannot find the desired PTY, the radio will display NONE FOUND and return to the station you were last listening to.

RDS Clock Time

Broadcasters can choose to send clock time information in the RDS data. This information can be used to update the clock time on the radio. RDS clock time is broadcasted once a minute. To set the clock press the RDS SELECT button. Then press and hold either the HR or MN button. If the broadcaster is sending clock time data the display should show "STATION TIME IS xx:xx". If the time is acceptable, simply continue to press and hold the HR or MN button until the display shows "TIME UPDATED".
