Hi, I just discover this site today while googling for an answer to why the subwoofer on/off setting disappeared from my head unit.

Hopefully someone in here could help me.  Not sure when the subwoofer  on/off setting disappeared as I have not needed to make any adjustments lately.  Obviously with the subwoofer off and no setting to turn it back on I cannot adjust anything related to the sub.  I know there was an on/off setting at one point I am just not sure how to get it back.

Thank you in advance

do you have pictures of the sound setting

Did you try reinstalling the firmware?
