How to enable NMEA output from C120W?

Chuck hi, thank you for the comprehensive reply. I've spent about six hours working through it thank you.

It would seem that in my system the AIS Layer Setup menu item does not exist:

==========

>Finally, the AIS Objects configuration setting within the Chart application page/pane being viewed must be configured to ON.

------
And, therein lies the problem:
The manual says:
Enabling and disabling AIS silent mode
In the chart or radar application:
1.2.Press the MENU button.
Using the trackpad, highlight the AIS Layer Setup menu item,
then press the trackpad right to select it.

But in my system the AIS Layer Setup menu item does not exist.

Continuing:

>Please click here to view a FAQ addressing the NO AIS problem reported.
>- Verify that the Chart application page's/pane's AIS Layer (MENU->PRESENTATION->OVERLAYS->AIS) has been configured ON.

My unit does not expose that. We have
Chart Application->PRESENTATION->CHART LAYERS->CHART LAYERS->AIS Objects, which are ON.

Went through the FAQs, thanks, no joy.

So the bottom line is
In my system the AIS Layer Setup menu item does not exist.

Tomorrow is another day. Ideas welcome...

Kind regards, Andy
