Mike -- Other than getting no digital track read out in the GPS window, nothing happens to my TruTrak ADI if the GPS signal goes away. For what it's worth, I also have not had the confusing indication mentioned in this thread.

Jim,

What happens to the ADI when the GPS goes off line or reception is too weak?

Subject: [LML] Backup DG equivalent

As a backup direction indicator on my Legacy, which also has a
2-screen Chelton EFIS system, I'm using the 2-1/4" ADI from Tru-Trak.
It's a bit of an odd critter, but if you buy it with the GPS and backup
battery options, it does give a heading (track, actually) indication
that's completely independent of your plane's electrical system.  It
also provides pitch and bank info.  Hard to find equivalent info from
2-1/4" instruments without spending a fortune.
