When I installed the top case on my 2017 F3T, the instructions called for downloading and installing radio update file s.19; I've downloaded it but don't want to install it until I know what it does. The section of the instructions concerning the software update starts with this statement:

"NOTE: The amplifier is plugged into output AUX which sets the rear speakers volume to maximum at all time(sic). This why the update installation is recommended."

I'm not using the amp or rear speakers as my wife and I use a MotoChello wired intercom/media center. Does this update give the operator control of the auxiliary output volume, or just allow control of the amp output volume?
