General
Automatic Volume Control (AVC) automatically adjusts volume level to compensate for ambient noise associated with motorcycle speed.
If the AVC does not adequately compensate for ambient noise (or if it overcompensates), enter the diagnostic screens.
Press and hold any two preset buttons on the front panel while turning the Ignition/Light Key Switch from OFF to IGNITION or ACCESS.
See Figure 1. Diagnostic group 1 (d1), the first of several diagnostic screens will appear in the LCD.
See Figure 2. Press the local/distant (LO*DX) button to cycle through the diagnostic screens. Stop at the AVC adjustment screen. AVC is displayed in the upper portion of the display, while the AVC level appears in the lower portion.
- To ramp the AVC up, press the MODE SEL switch UP.
- To ramp the AVC down, press the switch DN.
NOTE
Although the factory presets the AVC level at 2, it is adjustable from 0 (off) to 4 (most compensating).
After selecting an AVC level, repeatedly press the LO*DX button until the receiver reverts back to normal radio operation.

AVC Model Year Selection
Earlier model year motorcycles use a different type of AVC signal. The 2005 radio can be set to accept either type of AVC signal.
Enter the diagnostic screens to select AVC model year. Press and hold any two preset buttons on the front panel while turning the ignition/light switch from OFF to IGNITION or ACCESS. Press the local/distant (LO-DX) button to cycle through the diagnostic screen. Stop at the AVC model year selection screen.
A scrolling message is displayed in the upper portion of the display, while the current AVC model year selection is displayed in the lower portion. The scrolling message says, "Press "1" for bikes before MY2004.......Press "2" for MY 2004 or later bikes". Your selection is displayed in the lower portion of the display by a "1" or a "2". See Figure 3.
NOTE
The radio retains the AVC model year selection, however if power is removed from the radio, AVC model year selection defaults to MY 2004 setting number 2.
