compatible CDI for GNS-430W

[yvesg]

Hi folks, looks like I will upgrade the panel with the IFR GPS. I am looking at buying an affordable second hand CDI. A part supplier tells me that I can use a KI209 with the 430W... the installer tells me I absolutely need the one with the A suffix (KI209A).

Who should I believe?

It has to be the A.  The 209 will only accept composite input.  The A will accept composite or Left/Right.  The KI 520 will work also.  Be careful with buying used indicators.  Some models below a certain serial model or mod level are pretty much desk ornaments.

Does't the GNS430W provide the composite?

what I said above was based on other standalone GPS's that do not have a nav reciever in them as the 430 does, so it may be incorrect.  Normally the composite comes from a nav radio and GPS's use left/right.  There are also differences in the resolvers inside different indicators.  The A model basically has a relay to bypass the composite demodulator and can apply the Left/Right directly to the needle movement coil.

Thanks for your feedback. i found out that the KI209 would work but not to show GPS deviation. The diagram we were based on has a note stating this at the bottom. So all is clear now... to fully use the GPS potential, the KI209 is not the proper choice.

Thanks

you can easily find the GNS 430 install manual on the net

 

The non-A version of the KI-209 will not support the GPS Annunciate function 

 

In the unlikely case where you have a 400 or 420 (not 430), then you could use the Ki-209.

Thanks Alan but this one is not on the approved list.

Daver, the avionics shop that did the install happened to have a serviceable second hand GI106A that was taken out of a Cessna recently. I got it a bit cheaper than what bennett avionics sell these for so I am quite happy with it.

This unit provides full features support.

I may have a GI106A in the next few days if you are interested , Regards Alan...
