Playing the Radio PWR (Power): Push this knob to turn the system on and off. VOL (Volume): Turn this knob to increase or to decrease the volume. DISP (Display): Press this button to switch the display between the radio station frequency and the time. Press this button to display the time when the ignition is turned off. For RDS, press the DISP button to change what appears on the display while using RDS. The display options are station, RDS station frequency, PTY, and the name of the program (if available). For 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 you see the display you want, then hold the button until the display flashes. The selected display will now be the default. SCV (Speed-Compensated Volume): With SCV, your audio system adjusts automatically to make up for road and wind noise as you drive. To get to SCV, push the TUNE/AUDIO knob repeatedly until SPEED VOL appears on the display. Turn the TUNE/AUDIO knob to select MIN, MED, or MAX. Each higher setting allows for more volume compensation at faster vehicle speeds. Then, as you drive, SCV automatically increases the volume, as necessary, to overcome noise at any speed. The volume level should always sound the same to you as you drive. To turn SCV off, press SCV until OFF appears on the display. 3-88
