Wildhorsetrail Posted February 2, 2023 Report Share Posted February 2, 2023 I believe my best upgrade path forward is to remove a KNS 80 and a KX 170 and use the KNS 80 space to install a GPS NAV/COM. With the approximately 3 inches available, which box would you put in there? Garmin? Avidyne? King? Other? Quote Link to comment Share on other sites More sharing options...
ArtVandelay Posted February 2, 2023 Report Share Posted February 2, 2023 GTN 650, if you ever envision upgrading to a modern autopilot (GFC500). 3 Quote Link to comment Share on other sites More sharing options...

If you have an existing nav, a gnc355 is nice too (and less $$). I like having ils and VOR capabilities, but we don’t need 2 anymore and a waas gps. 1 Quote Link to comment Share on other sites More sharing options...

Wildhorsetrail Posted February 3, 2023 Author Report Share Posted February 3, 2023 Let's go a little deeper into the water. Here is a picture of the panel. I would actually almost rather put the GNC 355 mentioned above. But does anyone know of a GOOD nav/com that would replace the one I have below the KNS 80? That would give me a basic nav, 2 coms (GNC 355 as No.1) and a GPS. I'd be completely satisfied with that. Quote Link to comment Share on other sites More sharing options...

Pair that with the GNC355 GPS/COM and you’ll be set with dual com with one each GPS and NAV. 3 Quote Link to comment Share on other sites More sharing options...

If you want to save a little money but still get a recent nav comm, SL30 is also an option. https://sarasotaavionics.com/avionics/sl30-used can probably find cheaper, but this is reasonable for an idea. It’s “digital” too, so it can input into g5s as #2 if you want. Quote Link to comment Share on other sites More sharing options...
rbp Posted February 3, 2023 Report Share Posted February 3, 2023 I have e the 355 as #2. Very happy with it. But if you think you might get some additional newer Avionics in the next few years, consider a GTN650 Quote Link to comment Share on other sites More sharing options...

All you need for a GFC500 is a G5. There've been installs with a G5 and an IFD. An IFD 440 would be a good choice for a 3" GPS nav as well. 1 1 Quote Link to comment Share on other sites More sharing options...
rbp Posted February 3, 2023 Report Share Posted February 3, 2023 One thing most people don’t know about the GTN 750/650 is that it is possible to monitor the standby com frequency. So you can talk on com1 active, Put ATIS in the standby frequency and press MON, And you will hear both. So theoretically one could get away with a single 650, with WAAS GPS, VLOC/GS, And the ability to listen to two frequencies and talk on one. risky, but possible 1 Quote Link to comment Share on other sites More sharing options...

Pinecone Posted February 3, 2023 Report Share Posted February 3, 2023 Buy once, cry once. Teh 650 gives a LOT of capability. And can be the basis for a major panel redo if you hit the lottery. Quote Link to comment Share on other sites More sharing options...
N231BN Posted February 3, 2023 Report Share Posted February 3, 2023 That's a nice looking KNS 80, I would keep it over the 170B. Quote Link to comment Share on other sites More sharing options...
