Default Avionics Advice

Below is a pic of my current panel. I would like to install a used 430W where the 295 is. Then, I want to replace the DG with an electric EFIS such as a G5 or similar. I figure this will give me dual radios, IFR gps capability including an indicator through the G5, as well as VOR/LOC. Does this seem a sensible plan? Can I use the same indicator (G5) for both the GPS output and the VOR/LOC output from the 430?

Yes. Pressing the CDI button on the 430 should swap your indicator from GPS to VOR/LOC/ILS.

And you will need Garmin's GAD 29B so the 430W can talk to the G5's CAN bus interface.

Sounds like a good overall strategy for you.

But if you intend on keeping your airplane for 10yrs or more, I would seriously consider spending some more $$$ and get the GTN-650 instead of the GNS-430W. It is only a matter of time before Garmin stops supporting the G430W and you will wind up having to install a G650 anyways.

Just my 2cents.

I have a 420W talking to a G5 without a GAD 29b. From memory the RS 232 output on port 1 connects to the corresponding input on pin 4 on the G5. Works fine.

What about the ADS-B Out requirement? Are you considering upgrading to an ADS-B transponder? If so, you might want to take a look at the GNX 375 which will give you a GPS navigator and ADS-B transponder in one box for $8K--significantly less than a GTN 650. With the cost of a 430W around $4K and the possibility that they may be going extinct, it might be a good time to look ahead. Just a thought.

Appreciate all the good advice!

Yes, ADSB needs to be a consideration as well. I suppose I could go with the 375, then add an SL30 for nav and a second com radio. Lots to think about...

Default Upgrade

I would recommend getting the newest technology that you can justify/afford. Having lived through a few technology life cycles, I have learned the hard way that saving on technology is often a false economy when considered in the long run.

Looks like you will have a nice set up.

You will need a GAD-29 (not 29B, which is the certified, and more expensive, version) to get full functionality of the 430W into the G5. It also needs RS-232 for MAPX, which provides limited functionality, alone.

In answer to your questions: yes. I think this is a very sensible upgrade plan, although I think you'll want the GAD-29 as others have noted.

I fly a 430W/G5 combination IFR on a fairly regular basis and I'm very satisfied with it. I'm hardly a complete Garmin fanboy, but I think the G5 is really good gear. And I learned on a 430 so the fact that its user interface is (admittedly) a bit old school doesn't bug me. If you're not already experienced with the 430, you can get up to speed pretty quickly on it using YouTube and various aftermarket pilot's guides.

These threads always lead toward recommendations to spend more $ on newer stuff . But I think a used 430W remains a very good value and a very good option for your panel upgrade. There are a zillion 430s out there so I don't think you'll be orphaned any time soon. I'm ready to be proven wrong, and promise to revisit this thread in five years.

Now it's my turn to encourage you to spend more $$: if you're undecided I strongly encourage you to get the battery backup option for the G5. It's not that expensive and provides an enormous amount of redundancy. A total no-brainer in my view.
