Weird, My 2011 FLTRX-103 came with a Speaker Switch to turn off Front or Rear Speakers if added, or Both.
I wonder why the CVO doesn't come with a switch?
My '11 SERGU has this switch too. It allows you to hear the CB/Inter comm either through the speakers and headset, through the headset only or only the CB/Inter comm. through the headset.
I noted on the original posted photo, there is no 7-pin socket for a headset (mine came with 2 sets of helmet mountable earphones and 2 VOX boom mics). My socket is to the left side of the tank dash panel. I am guessing that this switch was not included because the stock radio does not have a CB/Inter comm?
Weird, but this is the third post I have read this weekend that marks pretty large differences in the '12 and ;13 SERG and my '11 SERGU, specifically heated seats and the CB/ inter comm if that is what the difference is.
