This system relies upon receiving specific information from these stations and will only work when the information is available. In rare cases, a radio station may broadcast incorrect information that will cause the radio features to work improperly. If this happens, contact the radio station. While you are tuned to an RDS station, the station name or the call letters will appear on the display instead of the frequency. RDS stations may also provide the time of day, a program type (PTY) for current programming, and the name of the program being broadcast. 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. 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, press the TUNE/AUDIO knob repeatedly until SPEED VOL is displayed. Turn the TUNE/AUDIO knob to select MIN, MED, or MAX. Each higher choice 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. If you don't want to use SCV, select OFF. DISP (Display): Press this button to display the time when the ignition is turned off. For XM™ (48 contiguous US states, if equipped), press this 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.
