Hello,

We plan to overhaul the panel of our good old PA34 Seneca.
Unfortunately, the 2 workshops from whom we requested a quote
disagree
: - one says the GNS530 we're buying can work with one of the 2
VOR/ILS indicators currently in the plane (these are "KI
something", one connected to a KX165 and the other to a KX175B).
- the other mechanics asserts we have to buy the specific VOR/ILS
indicator from Garmin (GI 106A).


If you requested an IFR-certified installation of the 530, they may
be telling you to use 106's because of the requirement to have the
mode annunciators. You could use your existing KI indicators but you
would then have to install a separate annunciator module. Garmin went
well out of its way to ensure that their units work with most cdi's
on GA aircraft.

You're right. Actually the one proposing to reuse our existing CDI
added an "MD41" annunciator.

Yes, that is what I was talking about.

From a technical standpoint, I understand I'll get a more integrated
use of a GI106 coupled with the GNS530.

Well... yes, in the sense that you save yourself the cost and panel space
required for the separate annunciator, but the cost of the 106 offsets the
savings, more than likely. From a technical standpoint the end result is
the same, except that the annunciator is usually placed at eye-level on the
panel (or as far up on the panel as possible), whereas the 106 has a flag
and doesn't get your attention the way an annunciator does, assuming
typical panel placement of a CDI. Whether or not this is a factor in the
decision is a matter of personal taste, I suppose...

From a price standpoint, the additionnal cost of the GI106 (around
500? vs the MD41) will certainly be offset by reselling the previous
CDI unit. I'll go for this new CDI then.

Thx for your help.

You're welcome, glad to be of help.
