Speed Compensated Volume (SCV): The radio is also
equipped with Speed Compensated Volume (SCV).
When SCV is on, the radio volume automatically adjusts
to compensate for road and wind noise as you speed
up or slow down while driving. That way, the volume
level should sound about the same as you drive.
To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio
setup menu.
3. Press the pushbutton under the AUTO VOLUM
label on the radio display.
4. Press the pushbutton under the desired Speed
Compensated Volume setting (OFF, Low, Med,
or High) to select the level of radio volume
compensation. The display will time out after
approximately 10 seconds. Each higher setting
allows for more radio volume compensation at
faster vehicle speeds.
