NARCO 121 NAV head audio connection

Hello all,
I am installing a NARCO 121 nav receiver. It will be wired to a Garmin GTR225 com with a built in intercom.

The audio out put of the 121 has a 50 mw and a 30 mw audio output, which one should I use?

This is in a 14 vdc system

Thanks

Hi rge,
You do not have an audio panel?
That's the right way to wire in a Nav-121 if available?
If not, you'll use the auxillary audio input and most likely the 30 mv output from the Nav-121.
I'm assuming you have the install manual? If not, i can help.
