Playing the FM/AM Radio (Models without navigation system) SUBWOOFER － Use the SUBWOOFER mode to adjust the strength of the sound from the subwoofer speaker. Turn the PWR/ VOL knob to the desired level (－6 to ＋6). Even if the adjustment level reaches －6, the subwoofer is not turned off. Speed-sensitive volume compensation (SVC) － The SVC mode controls the volume based on vehicle speed. The faster you go, the louder the audio volume becomes.
