Audible alerts.... or not?

[Glen Davis]

I have a G3X and a GTN 750 in my Mooney. I also have the remote transponder and audio panel.  This is a certified installation, not experimental. I am not hearing any traffic alerts, 500 foot alert, TOD alert or Obstacle alert. The only alert I hear is the auto pilot disconnect alert. I called Garmin and was told on a certified install, I should hear all those alerts. I called the installer and was told I would need to pay about $19,000 to unlock TAWS. So my qeustion for you with certified installs, what allerts to you hear?

@Glen Davis I have a G3X and 650Xi and get all of the audio alerts you mentioned. You definitely do NOT need to spend $$$ on TAWS to get the basic alerts.
 

Most alerts are redundant on the G3X/650Xi so I have everything activated on the G3X and the redundant alerts turned off on the 650Xi.  This is probably backwards but the way I chose to do it. It requires access to the configuration menus on both boxes, which is easy to access (hold the MENU/HOME buttons in and power up the boxes until the config mode displays). I don’t recommend doing this, especially on your GTN750, if you haven’t seen it before and don’t have the install documentation to guide you. It doesn’t take much to push a wrong selection and mess up some important systems interface settings.
 

I’d ask your installation shop why they didn’t activate the alerts. If they push back show them the G3X Pilot Guide sections that describe the alerts you are supposed to get.

There are enough of us here who have worked through this that can help you get to where you want to be.

Sorry, but your installer doesn’t seem to know what he’s doing. The alerts should have been configured during installation. Assuming everything is wired correctly, enter configuration mode, go to the sound configuration page and set up the alerts.

In a G3X installation, all the audio is routed through the G3X GDU and the G3X installation manual calls for only the G3X to be connected to the audio panel. If the GTN is also connected, you will likely get an echo when engaging Smart Glide (that’s how I found out that both of mine were connected.

Yup, mine are both connected as well. I was getting an echo on the 500 foot callout, which I then disabled on the GTN. I didn’t realize that isn’t in compliance with the STC so I just learned something from you, again .

Sounds like you are speaking from experience....

It took a lot of sleuthing and phone calls to Mooney to figure it out. The installations can be confusing because the installer has to read the installation manuals for each piece of equipment in the right order as some equipment installations require changes to wiring or configurations of other equipment.

Fortunately no! I studied the configuration documentation before jumping in to the systems so I’d know what to stay away from. My background makes me inclined to “tinker”, which is NOT a good thing in this case.
