I am having a GNC 255 installed. I am using the built in intercom and do not have an audio panel. I have not used the 255 yet and a question came up during install ...
I planned on using the built in COM/NAV audio mixing and only running the COM audio to the headsets, and using the front NAV knob to enable/disable NAV audio when desired.
The shop recommended that I run the COM and NAV audio separately, but run the NAV audio through a switch. They are concerned that the NAV audio wont be able to be turned off easily if I wanted to turn it off.
Anyone using the 255 with a similar setup have input on this? Does the internal mixing with the NAV knob work well, or would it be beneficial to have an external switch?
Thanks,
James
