That's general !
More specific, it's about the Garmin 500 with the Garmin GI-106A VOR/LOC/GS/GPS Course Deviation Indicator (CDI). First, I thought that this indication is coming as a parallel indication from the VOR/ILS receiver (KURS MP 2), but it's not.
I think (but it's more a guess and I didn't find any documentation at the first research) that the GPS being all about the positions, it could compute an ideal landing track, knowing of course the position of the runway (at least two points of interest).
About the precision, I personally think you cannot compare this kind of indication with the one provided by a classic VOR/ILS receiver.

You really should start a new thread with these questions instead of resurrecting a 5 year old thread. Mainly because, as you see, many people will not see your post and answer the original question.
I believe most analog indicators use either composite input (and have a built-in converter) or take in voltage signals that control the needles. Some GPSs will work with these, not sure about Garmin 500. The manual should have the pinouts.
