D180 AMS Audio Alert Output

I have DB38 Pin #31 (EMS Audio Alert Output) wired as shown utilizing the 10 kΩ variable resistor.

3581


The center terminal is connected to my Garmin GTR200, AUX MONO IN 1

The Garmin has an AUX 1 LO terminal as well, but there is no LO or Ground signal from the D180 paired with the EMS Audio Alert Output. Will I need a wire going to the AUX 1 LO terminal?


I also have a Skyview which has a similar audio out, however it also has a audio ground wire out. I have these feeding the Garmins AUX 2 MONO IN 1 & AUX 2 LO. The Skyview audio works fine.
