I have 2 new Simrads this year on my Whalers -- one 9" NSX and a 9" GO

I'm in the process of installing the GO, and the power cable has a blue wire that can be hooked up to an external speaker for the beeps. I haven't hooked this up yet, but I might in the future.

On the NSX, are you able to get access to the back of it to see if the blue wire is attached to anything? If not, is the volume on the unit turned up?
