Hi, The OE Pioneer HU T1814 has this feature called ASL ( automatic sound level) which is supposed to adjust the volume at higher speeds. There are 4 settings, off, low, med and high. I've tried them all and neither setting seems to adjust anything when up at highway speeds.
Does this feature work on anyone's xB? The manual only says that the ASL cannot be set until the vehicle is moving if the battery has been disconnected for whatever reason. Other then that it just says you can set it to off, low, med or high, but i don't notice any difference.
Is there a initial setup I must do?

Thanx
