Playing the Radio P (Power): Press to turn the system on and off. v (Volume): Turn to increase or to decrease the volume. DISP (Display): Press to switch the display between the radio station frequency and time of day. While the ignition is off, press this button to display the time. If your vehicle's radio has XM™ (if equipped), press the DISP button while in XM™ mode to retrieve four different categories of information related to the current song or channel: Artist, Song Title, Category or PTY, Channel Number/Channel Name. To change the default on the display, press the DISP button until the desired display appears, then hold this button for two seconds. The radio beeps once and the selected display becomes the default. SCV (Speed Compensated Volume): If your vehicle's radio has Speed Compensated Volume (SCV), the audio system adjusts automatically to make up for road and wind noise while driving. Set the volume at the desired level. Press this button to select LOW, MEDIUM, or HIGH. Depending on the radio, the selection may be SPEED VOL MIN (volume minimum), SPEED VOL MED (volume medium), or SPEED VOL MAX (volume maximum). Each higher setting allows for more volume compensation at faster vehicle speeds. Then while driving, SCV increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. NONE displays if the radio cannot determine the vehicle speed. To turn SCV off, press this button until OFF or SPEED VOL OFF displays.
